Yoyo Loach (Pakistani Loach) – The Care, Feeding and Breeding of Yoyo Loaches

June 21, 2014 by Robert Brand 79 Comments

Yoyo Loach Stats
Minimum Tank Size: 45 Gallons (205 litres)
Care Level: Moderate
Water Conditions: pH 6.0-7.5 Soft to Medium
Temperature: 76-82ºF (22-27.7°C)
Maximum Size: 6 inches (15 cm)

The yoyo loach (Botia almorhae), also known as the Pakistani loach, is a small fresh water fish native to India and Pakistan. The name yoyo loach originates from the fact that the marking on the fishes side resemble the word “yoyo”, although this becomes more difficult to see as the fish ages.

In the wild, they inhabit slow flowing streams or still waters, and this environment should be replicated as closely as possibly in the home aquarium. Yoyo loaches are highly adaptable to water types and can be kept in both soft water and hard water tanks, though they should be given more time to acclimate to hard water.

They will generally grow to about 5 inches (13 cm) in captivity and can live for over 20 years if they are well cared. Anyone purchasing yoyo loaches should understand that they are a long-term commitment, and most people will keep them for at least 10 years.

Housing

Yoyo loaches grow relatively large for an aquarium fish, and  at the bare minimum should be kept in a 29 gallon (131 litres) tank while they are young. A larger tank is almost always a better choice, and they will only really thrive if provided with a 45 gallon (205 litres) or larger. They tend to be a very active and aggressive fish (to each other), so they will quickly outgrow a smaller tank.

Another reason for keeping them in a larger tank, is that they are a social fish, and need to be kept in groups of at least five. If they are kept in groups any smaller than this, they will usually experience some level of stress and may begin to spend much of their time in hiding. Needless to say, a stressed out fishing in hiding is not very exciting to watch.

Any tank with yoyo loaches should also contain numerous caves to give the fish a sense of security. They prefer deep caves, with small openings that allow them to squeeze their entire body into it. In fact, it’s not unusual for yoyo loaches to regularly get stuck in caves, and you should always check during a water change to make sure that none of them require rescuing. They will generally ignore any large caves or open rock enclosures that their cousins clown loaches are notorious for piling into, but there’s no reason to ignore these rock formations in a tank containing yoyo loaches.

Instead of buying expensive ornamental caves, you can actually quite easily make caves at home for one tenth the price. All that is required is PVC pipe, aquarium sealant, and some rocks or sand. Using the aquarium sealant, simply glue the sand or rocks on top of the PVC pipe, and once it dries, you have a ready-made cave for your yoyo loaches.

As a rule, yoyo loaches tend to be docile towards other species of fish, and aggressive fish should be avoided. That’s not to say that there won’t be some disagreements between the loaches, and often an alpha fish will become established within a complex pecking order. But they will rarely ever show any aggression to other species of fish that they share a tank with. If they are kept with an overly aggressive species fish, they quickly begin to spend much of their time in hiding. Some have been known to even go into permanent hiding and ignore food – which generally does not bode well for the health of the yoyo loach.

After the aquarium has been set up and a suitable number of caves have been provided, it’s time to choose a filter. The most economical choice is usually an HOB (hang on back) filter. While a canister filter is often more effective at keeping a tank sparkling clean, it is also far more expensive and is really only required for larger, messier fish. If you need extra filtration, then a sponge filter can be used in conjunction with a HOB filter, which will help to filter the water.

I would strongly recommend choosing an Aquaclear Power Filter for a yoyo loach tank. This filter combines excellent filtration with a durable design, and it will keep your tank sparkling clear for years to come. You can also read the Aquarium Tidings Aquaclear Filter Review here.

Feeding

Yoyo loaches are omnivores in the wild, and should be fed a similar diet in the home aquarium. Their main diet should consist of a high quality flake or pellet food, and should be supplemented regularly with live or frozen foods. I have used Hikari Sinking Wafers with great success in the past, but any sinking food will work for them.

One of their favorite live foods is snails, and they will completely wipe out a tank’s snail population in a matter of days. Some other live foods they enjoy include mosquito larvae, blackworms, daphnia and brine shrimp. If you are culturing mosquito larvae for your yoyo loaches, always be sure to check local regulations, since this is illegal in many states and provinces.

If live food is unavailable, then they will also relish any frozen foods that can be provided. Their favorite frozen foods are bloodworms, daphnia or brine shrimp. These should always be defrosted first, and they can easily be defrosted in a small plastic container with some warm tank water. After about 5-10 minutes in the warm tank water, they should be  ready to feed to the loaches.

Breeding

It’s surprising that for a fish that adapts so well to life in an aquarium, that there are no confirmed reports of it breeding in captivity. There has always been the occasional claim that someone has successfully bred yoyo loaches, but at this point no accounts of breeding have been confirmed.

In fact, even fish farms have had difficulty breeding yoyo loaches, and some have been experimenting with hormones to trigger breeding. At the time of the writing of this article, there were no farms that mentioned reliably breeding yoyo loaches.

    Do we know if they are live bearers or not? As I received a shipment of them and later found a very small baby in a filter sock…

      Hey Chelsea,

      They are definitely not live bearers, and what you are describing isn’t too uncommon. Quite often newly hatched fry will be sucked up into the filter. If they survive the trip into the filter, then they can often live for short periods of time in the filter. You may not see any other fry, since if they aren’t protected by the filter they are often all eaten.

      I’ve found fry in my filter numerous times, although never Yoyo loaches. Most of the time I find bristlenose plecos in my filters.

      I have 2 to yo-yos in my 55 gallon community tank. They are about 4 inches long now. I’m thinking it’s a male and a female. I think the female has a lot it eggs inside her, it is lighter in color than the other one. She has gotten fat. So is the male yo-yo darker than the female. This male is also starting to attack my Angelfish trying to bump & suck on them.

        I too have an extremely fat yoyo. We have 4. All the others are slim. I’d love to know how to determine the se. Of them. They are all over 4 inches long.
        I wonder if the fat one is a female and pregnant? How can you tell?

          The females don’t get pregnant, but they do become swollen with eggs. Generally speaking, there is nothing be concerned about unless it becomes very bloated, which may mean the fish has bloat. Does is appear to be sick in any way?

          To sex them isn’t too difficult IF your Yoyos are of mature age,and at 4inchs long I’d say they are,you need to look at the barbels,males will have reddish looking barbels whereas females don’t,ahhh I’ve just noticed how old your comment is,my apologies bug I’ve answered in case someone else has similar questions,so what happened with your yoyo?
          Also females have become gravid in captivity but it seems getting her to spawn is the tricky part,and the male can’t fertilise the eggs until they’ve been spawned so sadly most times the female reabsorbs the eggs,or god forbid she becomes egg bound,but Yoyos are also prone to bloating,to check you can feed blanched peeled and mashed pea which will help,this is also true for many other freshwater species too!
          ive had great success using a certain tactic with my cory cats that I’m hoping to try out with my 1 male and 2 female Yoyos to see if I can’t trigger spawning reliably,wish me luck!

      They are egg layers, but I’m not sure of much beyond that. I’ve looked through every book and paper I have, but no one describes their reproductive methods beyond simply stating they are egg layers. I have seen my females become heavily egg laden in the past, but I’ve never seen any eggs actually laid. Let us know if you successfully breed yours though.

    Thanks for the info, very informative. I have a yoyo loach that is about 5 inches long. not sure of his age, but he is quite fat. He’s a very boisterous eater, wrecking plants and scaring everything in his path. Yesterday when I fed him he was more boisterous than usual, he seemed to be thrashing about recklessly and flipping from side to side, actually wearing himself out, but calmed down after a while and was ok…not nice to watch! He did it again today after feeding and so did my bristlenose! it’s starting to worry me. I am feeding a variety of food, eg flake, algae wafers, brine shrimp, shelled peas, dried bloodworms, live mosquito larvae and sinking wafers, not all at once though, maybe a combo of 3. They are in a 170ltr tank with other fish, tetras, rummynose, glass cats, dwarf gouramis, an upside down cat and rc shrimp. The water parameters are PH 7.5, am – 0, Nitrite – 0, nitrate – 5ppm. Weekly water changes with tank water. Not sure about hardness. It seems to be only at feeding time which is weird, any ideas?

      I’ve heard of this before, but never experienced it. From what I’ve heard, this behavior is due to a lack of hiding places in the aquarium. Do you have plenty of caves or other nooks for him to hide in? I’ve heard that they like to retreat to a hiding place after eating, and if they don’t have one, they can sometimes go nuts.

      If you do have hiding places, then I’m not sure. You sound like you’re providing great water conditions for it, and I’ll ask around a bit to see if I can find anything else out.

        He has lots of places to hide Robert, a bristlenose log, a large cave with some cosy nooks & lots of plants. Some have suggested he could be either constipated, have flukes or internal parasites, or even be a gravid female. I have just put him in quarantine with a dose of epsom salts & no food for a while. I posted some photos & a video of him on a forum…..here is the link…

          I watched the video, and my money is on the fish flashing. It looks like something is irritating it, and sometimes it’s actually tied to the food. Flake foods can sometimes irritate their gills, and powder will become lodged in the gills after eating. It generally doesn’t signify anything that you should be concerned with, though I would recommend changing the food for a few days to see if the flashing stops.

          If it doesn’t change after you try a new food, then you may have to consider that it might be parasites. Though since the flashing only occurs after feeding, my guess is that the food is irritating the fish. I hope this helps.

      I’ve never experienced yoyo loach fry myself, so you must be doing something right. My only advice would to treat it like any other fry. Keep the water as clean as possible, offer it a variety of small foods that it can easily eat (baby brine shrimp, microworms, or crushed up flakes), and you may also want to consider getting a breeding net to keep it in. Most loaches aren’t know for eating their own species fry, but it’s better to be safe, than sorry.

        Old comment, I know, but I’ve found that the best way to keep fry alive in a community tank is to have about three times as many floating plants as you think you need. If you can get a start from a very mature tank (or better yet, an outdoor one), salvinia is *amazing* — the fry love the shelter of its roots, it grows very fast, and it seems to be particularly good at developing communities of microbiota which the fry chow down on (this is why getting some from a mature or even “dirty” tank is ideal). I don’t have to feed the fry anything special, they graze on things I can’t see until they’re big enough to compete for the flakes with everyone else.

        Amazon frogbit is *excellent*, as it forms layers of leaves which can hide the fry from both above and below. I have platys breeding regularly in my blackwater tank along with danios, glass catfish, and a dwarf gourami, and none of the fry survived until I put the frogbit in. Now there are three or four tenacious little guys out of every batch hanging around — not a lot, but given the curiosity and voracity of that tank’s residents, I’m still pretty impressed!

      I have to admit I’ve never tried crushing up microworms before. That must be an interesting to attempt. And like you, I can’t recommend Java moss enough for any breeding tank. It provides an excellent hiding spot for fry, and a ready food source. It’s great to have it with fish fry.

    Hi,

    We have recently purchased a tank from someone and inherited the fish with it. There are two of these loaches in the tank and I have noticed that one of them has a very swollen belly, I wondered whether this could mean eggs? We received no information about these fish and it appeared as though the previous owner took little care of them as we had 4 other fish (catfish, black shark and 2x plecos) that we have since had to take to a proper aquarium due to the size of them. Plus the tank was a state when we got it. Just wondering what to do regarding the loach though, I have done some research about fish pregnancy and we have bought a birthing tank just in case. Can anyone advise?

    Thanks

      It could be from many different things, but if they were kept in poor conditions it’s mostly likely bloat. Swim bladder disorders and egg binding are relatively rare in yoyo loaches, so I would focus on treating it with antibiotics. If at all possible, I would put it in a separate tank while you treat the fish. Also, try and find antibiotic you feed to the fish, and not one where you just treat the water.

      I would also try to feed your fish blanched and shelled pea, which often clear up swim bladder disorders. While I don’t believe it’s that, it’s still worth trying.

      And finally, focus on giving it the cleanest environment possible. I would try for two water changes a week of about 10-15% each, and test the water regularly to make sure everything is withing healthy parameters.

    I recently considered rehoming my two 3″ yoyo loaches because they eat portions of the new leaves that grow up from some of the plants, leaving the remains torn and ragged but I had a change of heart because they are as happy as puppy dogs. So now I just want to add more types of plants that they are less likely to feed on. Any suggestions on which type of plant that might be?

      Some very tough (as in hard to eat) plants that thrive in almost any water conditions are anubias nana, Amazon sword plants, Java Ferns, Java moss, and hornwort (very messy though). Java ferns are really great, since it’s rare for any fish to really want to eat them, and Java moss is nearly indestructible.

    I have 5 yoyo loaches. Absolutely love them and their antics. And they get along amazingly well in my 60gallon hap/peacock cichlid tank. 2 of my loaches are rather robust in the body. A fair bit deeper in the girth and broader across the back then the other 3. Though their just as active and playful. Am I safe to assume those are the females? Both are very heavy in the belly right now… would they be “expecting”. One of the slimmer ones of the 5 appears to be the dominant and pretty much gets ehat ever he wants like choice of hiding space etc. I’ve never research loaches beyond compatability and care. Now I’m excited at the (although slim)possibility of babies! So I’m going to take some of the actions you guys have mentioned and hope for the best ?

      They may very well be egg laden females, but it’s almost unheard of for yoyo loaches to breed in a home aquarium. Which is too bad, because these are such great fish, and they would be even better if you had the chance to raise some fry. But you never know – you might just be the first. Be ready with lots of pictures if some babies show up. 🙂

She is very protective of the log now not letting any other fish in or near it. I’m hoping I get some to hatch. It’s a huge tank with plants and logs in it for hiding. If I get baby’s we’re can I send pictures or videos of of them to cause it would be neat if they hatched and survived.

    Hi robert. Love your tips on keeping your loach fish happy. I have had a pair of loach, for two weeks now, they are lovely to watch. I am a little concerned about one of them, he’s hiding alot, but when they feed the two of them may seem to be dancing a round together up and down the tank. This morning I noticed one was on his side and moving his fins very fast, I helped him to lay on his tummy, he swam to the top of the tank, had a little swim then flouted to the bottom again. And now he’s been there for a while up right. I have fresh plants in my tank, rocks in my tank, but no caves. I am feeding them flakes also I have live snails in my tank. What else can I do to help them, water fine.

      I know clown loaches sleep that way, but I can’t recall ever seeing one of my yoyo loaches doing that. I’ve seen them sleep in other weird positions that have freaked me out though – like sleeping face down in one of the caves. Are there any other signs of illness beside that? Swollen belly? Any spots that look weird? Red tip on its nose?

        I have 4 Yoyo loaches, they all sleep on their sides. When they first started doing it, I was sure they were dead. It still makes me crazy when they do that. I have one that is fairly large, and I assume it’s a female as her body shape is a little different and her belly is larger than the other smaller ones. I have them in a 46 gal. bowfront but am cycling a 75 gal that they will go into. I have already moved plants and rocks over to the bigger tank so there’s no hiding places for them right now. I personally, love the tank empty (of rocks and plants, lol, not water) as I can watch them play. I don’t plan on getting any more of them though, as I have pool filter sand in the new tank and would like to have some snails to help keep it aerated. They adore snails for diner.

          When I had yoyo loaches and dwarf puffer fish, I actually had a small aquarium in a window with nothing but snails. They loved having daily snacks of snails in their aquarium. And you’re not the only one to have a heart attack from your loaches sleeping on their sides. lol

          It sounds like you’re giving them a great home. I wish more people in the hobby gave them that kind of home.

    Hi. I have 3 yoyos,and have been keeping them in a 165 litre community tank. They are happy, active, very fat, and have voracious appetites, so I call them the three little pigs. I recently got a 400 litre tank, and yesterday moved the three little piggies over to it. They just loved it! Exploring every item and vigorously fossicking in the gravel. By evening they were doing a twisting swimming dance, the three of them intertwining. This morning they are noticeably thinner, and there are eggs plastered over all the tank walls. I guess they REALLY liked the new tank! It will be interesting to see if anything comes of them.

    I have a Yo Yo that is 15+ years old. It lives in a 90 gallon tank. It is the friendliest fish I’ve ever had in my 60 years of aquariums. He loves my rather large angels due to the eggs they lay!! It is at least 5″ long and FAT! I say “it” not knowing if it is male or female. Very active and again friendly to all in the tank.

    I recently purchased my first Yo Yo Loach to help rid my tank of snails. He didn’t seem at all interested in snails. I don’t know if his behavior is normal, he will sometimes be on his side breathing rapidly so I’ll push him over and he’ll do this funny swim like a jerky movement. It’s going on day 6 he’s still here but not eating a lot, if the catfish see him eating, they’ll push him aside and eat so I’ve tried putting a small pellet in his hiding spot. Does he need a tank mate.

      First of all, how large is your tank? And have you tested your water lately? It sounds more like a water problem or illness right now.

      Let me know those stats, and then we’ll go from there.

    Hello, I have a yoyo loach problem. I have 2 of them and they were completely happy and playing 2gether, then I had an ich problem with some neons. I used half dosage bc of the loaches the ich was gone but one of the neons died and I saw a loach eating him. Then all of a sudden my one loach had a red mouth almost like lipstick. went to lfs did a water sample and they said nothing to be concerned about. They then told me to get melafix the redness has cleared up but the fish is sluggish, and constantly being chased by the other loach. i have not seen him eat and its been almost 2 weeks since i noticed he was not normal. seems as if some of his bristles are shorter then the other one. He def lays down a lot and i know he is not dead bc he keeps popping up and has gill movement. is he a goner or is there something else i can do to help him? tank is 45 gal, multiple hiding caves, other fish are tetras and dwarf neon rainbows.

      I’m sorry to hear about your loach. Are there any symptoms right now? Is the fish bloated or is there anything growing on him?

      I wouldn’t say your fish is a goner, but you definitely need to figure out what is going on. If he is sick, then you need something stronger than melaflix. Is there any way you could send me an e-mail of what the fish looks like? admin@aquariumtidings.com

    My two yo-yos have been writhing around each other this past few days. I found this sight to see what might be the problem since I had researched and found they haven’t been proven in captivity breeders. I’m excited to see what becomes of this. Also, I’ve got to add after seeing some comments to the sleeping positions….one of mine has been named Faker due to the fact he has freaked me out sleeping on his back. Got eyeball to eyeball a few times just to have him pop us and scare the crap out of me. I inherited one with my tank and the second from a friend in the hobby that just decided she didn’t want him. They are quite entertaining. Glad to have them!

      I think we’ve all been there with the ‘faking’ yoyo loaches. One time, I was getting ready to scoop a yoyo loach out, when it leapt up and swam away. lol

      But as for the breeding, some people can get them to mate, but they never seem to actually lay viable eggs. It would be amazing if you could get them breed. You’ll have to let us know if you end up with any fry.

    Hi Robert ! I have 4 Yo-Yo Loaches in a 8′ 250 Gallon Aquarium. I have had them since they were less than an inch in size, with me for about nine months now. I love watching them. This tank also houses 20 Discus, 100 neons and several species of Cory cats. My Yo-Yo’s always appear to be “cleaning” my Discus. The Discus are never harmed, no markings on their bodies and they don’t seem to mind it. Is this a trait of the Yo-Yo?

      Unfortunately, they’re probably not cleaning fish, but are most likely feeding on the slime coat. The slime coat is very important to a fish’s health, so assuming I’m right, then you should probably be concerned about their behavior. While I’ve never seen Yoyo loaches doing this, it’s very common for fish like plecos to feed on the slime coat of flat bodied fish, and having witnessed this, it’s why I think it’s occurring here.

      If it’s at all possible, I’d try to rehome the Yoyo loaches in another aquarium, since over time, the lack of a slime coat will open the discus up to infection.

    I’ve got a tank with a school of 12 aggressive penguin tetras. They’ve been in a single species tank for 6 months after proving to be too rough to house with my other fish, but without external distractions their routine squabbles inside the school have gone too far and they have been bullying the smallest member of the school to death. Today bullying victim number 3 died and I’m determined to do something to stop it from happening again. They have lots of room and cover so I think they need a larger tankmate to give them something else to think about instead of constantly squabbling – of course I only want to add a safe, peaceful tankmate, not anything that would be an actual threat. I’ve been a bit stuck trying to work out what would be suitable. The tank is planted so I don’t want a barb species that will trash my plants or a cichlid that will dig them up. Gouramis and angels would likely have their trailing fins nipped off in no time so they’re out too.

    Someone suggested to me that yoyo loaches might be a good match so I have been researching them and I really like what I see. I think the parameters I keep my tetra tank at match the requirements for yoyo loaches, plus the tetras stay in the top third of the tank and won’t chase any food that falls over the half way mark so their territories hopefully won’t overlap too much, and it would be nice for this food not to be wasted, not that I would consider a bottom dwelling fish to just be a tank cleaner. There are a ton of snails (clean up crew for the fallen food) and I already have sinking catfish food, worms, and so on so I won’t need to change much to keep them well fed. The tank has peagravel with plants along the back and fine sand in the front half, with a few lumps of driftwood and smooth stone. I gather its probably not enough cover to satisfy a loach but I have PVC pipe I can add if necessary, and there is a very shady hollow under one of the driftwood pieces.

    So my concerns are, will yoyo loaches be able to shrug off any rude behaviour from these tetras? I wouldn’t want them to get too bashed and bullied. The other issue is that my tank is only 4 feet by 14 inches deep by 16 inches tall, which I think is around 180lt and I’m a little worried this might be a touch small for a group of six adult sized loaches. Sadly I can’t find any zebra loaches in my region as I think they are a bit smaller and might fit better. I’d rather try a big group than skimp and only get 3 or 4 as I want them to grow up happy, and I don’t intend to add any other fish. Do you think yoyo loaches could be happy in my tank?

      While adding bottom dwelling fish will likely not cause any problems, it also won’t solve your aggression issues. One of the best pieces of advice I can give is to use tall ornaments and plants to break your tank up into distinct regions. Once lose line-of-sight with another fish, the aggression often ends. I have used this successfully in many of my more aggressive tanks, and some are split up by rock formations, or tall and floating plants.

      As for the choice of fish, your tank should be large enough for yoyo loaches. But catfish would also work just as well, and you wouldn’t be pushing the limits like you would be with a full yoyo loach.

      As long as they’re not too small, they will do fine with a blue gourami while they grow. But you’ll need to upgrade their tank in the future.

      They are pretty notorious for hiding, but the aquarium is way too small for them. And do you know what killed your yoyo loach? Was it another loach? It sounds like they would be better in 30 gallon if at all possible.

      Generally speaking, different sized yoyo loaches mix quite well together. I’ve seen many small yoyo loaches being kept with much larger yoyos, so you shouldn’t have any problems. I would just keep an eye out for any aggression – not usually a problem with yoyo loaches, though there can be some dominance issues when kept in larger groups.

    I’ve had a my loach nearly 18 years has lived in a cold water tank with Black Moor, for the last 5 years doesn’t really bother them much just chases them occasionally. Just hides away and minds it’s own business, still fairly active at night. Always made sure it has somewhere it can hide it loves tiny small spaces to hide in.

Also if there’s no “reported success” with amatures breeding where would I send the pictures to prove that I have breed them successfully?

    I have a 75 gallon community tank . All the fishes are here more than 1 and half years. There’s 4 gold fishes, 4 angels , 4 giant black mollies, 4 golden snail and some sword Amazon plant . I had a pleco that grew to 13 inches and used to feed on most of the food depriving other fishes. It was never aggressive or bully but everyone said I need to get rid of him 😭😭😭😭. So I sold it . After it’s not present in the tank water started to get very unclean fast, weekly changing seems to not working.

    So I bought 4 yo yo loaches . They are with me since last 2 months and growing. They are very playful ……they hide, they swim, they play, they jump out of water and they climb by the tank wall out of the water to jump into the water. But from the very first day till now when they rest they flip sideways like their right side towards bottom and left towards surface ……vice versa. At first I thought they’re getting sick and started treatment. But to my surprise this behavior didn’t change. All four are doing same. As if sleeping on their one side .

    Now my question is ” is it normal behavior for them ?” . I have plenty of places for them to hide and to play. My gold fishes doesn’t give a damn to anyone in the tank, angels swim everywhere , mollies are active . So the tank is healthy environment. Please let me know the way my Yo Yo are behaving normal or not.

    I had been cycling up my 55 gallon tank for cichlids, working on my stocking list for MONTHS and finally was happy with it, when I stopped in at a pet shop on my lunch break and found myself unable to leave without this goofy dork of a loach who was hanging out all alone. I had never seen them before, had no idea about what they needed, but I saw it from across the room and just stopped in my tracks, like WHAT IS THAT?! and the shop owner said my tank would be fine for them and . . . yeah.
    Now I’m planning a tank around yo-yo loaches — these things happen.
    Tweekerdoodle is the first fish that our terrier has noticed, and she can’t stop watching him. Family members who are meh about my other tanks stop by his every time they pass to watch him and coo nonsense at him. I believe he may be on his way to becoming a minor TikTok star, even — these are fish with MAJOR personality. I’m planning to stock a fish tank at the agency I’m interning with a group of these. I might start a fan club.
    Anyway I don’t really have any questions, just encouragement for anyone who’s on the fence about yo-yos — DO IT. They are delightful. And totally worth having to re-plan an entire tank’s stocking for 😉

Like the Clown Loach, this fish spends its time at the bottom of the aquarium actively looking for snails with shells to kill. However, if you are planning on getting this loach to kill your freshwater snails, make sure to have a large aquarium to house it. The Yoyo loach can grow up to five inches and should have an aquarium of at least 29 gallons. After a while, you may have to purchase a larger aquarium to keep up with how fast the loach is growing. For the loach’s diet, you can feed the fish pellets that float to the bottom. The loach tends to eat just about anything available. When it comes to food, they are not picky at all! Make sure to take inventory of what fish you have before purchasing the Yoyo Loach. The loach tends to be very aggressive as it grows bigger.  […]
