The term Mexican dwarf crayfish is used to encompass several species (Cambarellus) of small, peaceful crayfish. This also includes the relatively new orange dwarf crayfish, which is rapidly becoming one of the more popular species of crayfish to keep.
Dwarf crayfish are native to Mexico and the southern United states. They primarily inhabit streams and small rivers, though they can also be found in ponds and lakes. They tend to prefer slow moving waters, and are mostly found in the shallows.
They remain relatively small in the home aquarium, and the largest species of dwarf crayfish will only grow to about 2 inches (5 cm) in length. On average, they live two to three years in captivity, though there have been recorded instances of them living longer.
Housing
Dwarf crayfish are undemanding when it comes to housing, and a handful of them can be housed comfortably in a 10 gallon (45 litre) aquarium. However, if you want to keep more than two or three of them in an aquarium, then you should consider a 20 gallon (91 litre) long aquarium to be the minimum size.
Any aquarium containing dwarf crayfish should include numerous hiding places. Crayfish molt regularly and they require a place to hide until their shell hardens again. Until their shell hardens, they are completely defenseless against other crayfish and fish in their tank – so include hiding places if you don’t want them to get eaten.
You can tell that a crayfish has molted by the fact that the substrate of the tank will be strewn with what looks like crayfish body parts. Don’t panic if you see this, since it’s just likely molted out of its old shell.
When choosing a filter for a dwarf crayfish tank, it’s important to choose a high quality filter. They tend to be more sensitive to water conditions than other crayfish, and they do not handle ammonia or nitrites well. Usually hang on back (HOB) filters make the best choice for dwarf crayfish tanks, though sponge filters can also make a good choice. If you do decide to use an HOB filter, you should cover the filter intake with material to ensure that no crayfish hatchlings are sucked up into it.
Something unique to dwarf crayfish is that they can usually be kept without incident in community fish tanks. They are a relatively non-aggressive species of crayfish, though it should be said that there are exceptions to every rule (they may also prey on small fish like neon tetras). Because of their small size, they should never be kept with large fish, or other large crayfish. If they are kept with either large fish or crayfish, they will quickly become prey.
Feeding
Mexican dwarf crayfish are omnivores, and they will eat just about anything that they can get their claws on. In the home aquarium, they should be fed a regular diet of a high quality sinking pellet, along with regular feedings of live or frozen foods and vegetables. I recommend feeding them Hikari Algae Wafers, which are perfect for crayfish.
When choosing their live food, make sure that you only select bottom dwelling live food. This can include blackworms, brine shrimp, gammarus, earthworms and snails. Live foods that are top or mid dwelling like mosquito larvae and daphnia will go uneaten.
Dwarf crayfish will also appreciate the regular addition of vegetable matter to their diet, and their favorite vegetables are shelled peas and zucchini and cucumber medallions. All vegetables should be thoroughly cleaned and blanched prior to adding them to an aquarium. They will even accept dried aquarium plant cuttings and leaves, though that can quickly foul your aquarium if you’re not careful.
Breeding
Breeding dwarf crayfish is relatively easy, and will usually occur with no intervention from the aquarist. The only true requirement for breeding is to make sure that you have at least one male and one female in the tank.
When breeding is initiated, the male pins down the female and deposits sperm near her sperm receptacle. The female will carry the eggs from anywhere between one to four weeks. The length of this is highly dependent on the temperature of the aquarium. After that time, the female will lay between 20-60 eggs while hiding in a cave or underneath an overhang.
The female will then fold her tail under the body, and fertilize the eggs while forming a mucus sack around the eggs to protect them. The female will carry the eggs for four to five weeks, while using her appendages to keep the eggs clean of dirt and well oxygenated.
Once the eggs hatch, the baby crayfish will remain with the mother until they are ready to set off on their own in the aquarium. If you want a high hatchling survival rate, then you should add numerous small hiding places for the baby crayfish.
The hatchlings don’t have any special food requirements, and will often scavenge for food on the aquarium substrate. Just make sure to add food to the tank at several locations, so that the baby crayfish have a chance to get some of the food.
I wonder if you have any experience caring for freshwater shrimp? Not a whole lot of content to be found. Mine are doing well, but would like to sharpen my knowledge.
What kind of shrimp are you looking at?
MY crayfish is a killer crayfish (this type) and was wondering what fish it wouldnt kill. Like a red tailed shark
I have a lot of tetra’s in my tank with 2 crayfish. The good thing is from the time i bought them home i never had to clean up decaying matter from my tank! The crays do it for me.Dead Leaves, dead(or dying) fish! Try and keep fast swimming fishes especially the ones that dont dwell on the bottom much. My crays and plecos dont bother each other though!
One of the hardest things about crayfish is finding suitable fish tankmakes for them. But it sounds like you’re making it work, and they are great for cleaning up everything in the tank. Who needs snails when you have crayfish.
My dominant CPO and Bristlenose frequently got into it over food. My CPO got the shit kicked out of him pretty bad, the last fight may have left him with brain damage, and a screwed up eyestalk. Day 3 of recovery, his future is still very uncertain.
could i buy 3 more tetras and a betta and get rid of the last guppy?
A betta would be easy prey for a crayfish – especially if it’s male. It can’t swim very fast, and it wouldn’t take long for a crayfish to hunt it down. As for the tetras, if some have already been eaten in the past, you’re just condemning them to death.
No none of my tetras have been eaten
I thought that you said he ate your neon?
Well then I didn’t mean it that’s the only think that he hasn’t touched?
If the tetras are fine, then they should generally be safe. It’s always a risk when you crayfish has developed a taste for fish though. So add new fish at your own risk.
Ok thanks!!! If. I wanted to breed the crayfish how can I tell if it’s a boy or a girl? How long does it take for their shell to harden. You have been a huge help!
The molts generally last for a few days, and I found a great little diagram to show how to tell a male from a female.
How many babies usually end up hatching in the end? My CPO had tons of eggs and now that they appear to have hatched and are still hanging on to their mom, there doesn’t seem to be very many. In fact I was concerned that she was simply no longer pregnant. But after studying closely I determined that there are at least a few in there. So what is normal? How many usually end up making it all the way to the end of the gestational period??
They tend to have fewer eggs than their larger crayfish cousins, and I would estimate that on average they would have between 20-40 eggs, though it is possible for them to have more. While a few losses are inevitable, most of the eggs will normally hatch and make it to the hatchling phase.
Are there any fish in the tank, and are there plentiful hiding places? Does your crayfish feel comfortable being out, or is it normally hiding? Hiding could be a symptom of stress, since this species usually walks around even during the day.
If I use a sponge filter, what about aeration? Do I need an air stone in the tank?
Sponge filters actually aerate quite nicely on their own. Just leave a little space between the plastic tube on the top and surface, and the bubbles should provide more than enough aeration for a normal tank.
Would It be okay for one to be with a goldfish
As long as there are plenty of hiding places for it, it should be fine. Otherwise it could be in trouble when it molts, and while goldfish aren’t the most aggressive fish out there, there’s a good chance it would still try to eat it. But deep caves for it to hide in will help to solve this problem.
I got a 100L tank, with just 1 crayfish in currently. My local pet shop has 3 colors all the same kind of crayfish. Appearance wise. So i was wondering is there a difference besides the color, as my current crayfish is as passive as they come. I can pet her all i want and she’s never aggressive. But she doesn’t molt anymore. Or hasn’t for a few months atleast. So was thinking of getting a second crawfish. A blue or white one. So my question is. As the dwarf crayfish is friendly to some extend. Does it translate to the entire branch of that specific species regardless of color?

Most crayfish have relatively similar requirements, though some do better in cooler water than others. And what you have doesn’t look like a dwarf crayfish. Were you told that it was a dwarf crayfish, because it doesn’t look like any dwarf crayfish I’m familiar with.
As for the colours, they don’t matter too much unless you’re attempting to breed the crayfish. Some species do tend to be more aggressive than others, and I haven’t had great luck keeping electric blue crayfish together with any of the North American crayfish (usually reddish like yours.) You should be aware though there’s a real risk of cannibalism in a tank the size you have. So you need to consider carefully if you want to risk your current crayfish, or your new crayfish.
And crayfish’s molts slow down as they age, so you should expect one in the next several months. Also, they become incredibly vulnerable during a molt, so you should make sure you have plenty of deep caves for it to hide in from a new crayfish if you decide to get one.
Thank you for the very informative article…..
Advice needed 🙂
I notice my crayfish has eggs and the eggs are by the swimmettes..
Are these eggs fertilised and should I isolate the female ?
Thanking you
Is the female being kept with any males? If so, then she is most likely pregnant. Also, females can store sperm for several months, so even if there are no males, it’s possible the eggs could be fertile. What colour are the eggs currently?
And you should isolate the female if you want to raise any significant number of hatchlings. The tank should also include lots of small hiding places, or you’re going to experience rampant cannibalism.
Hi.
Thanks for your reply .
The eggs are black in color ..and yes there are males present . I did separate her and now have her in a separate aquarium.
Thanks once again ..We sure benefiting from your experience
Warm regards
Bred successful have about 50 babies now about 2 months old 5 cm big
Will the mexican dwarf crayfish eat your planted plants? Will they disturb other tankmates when they’re sleeping?
They will eat some plants, but they won’t devastate aquatic vegetation the same way larger crayfish will. If you place some fast growing plants in their tank like elodea, hornwort, or hygrophila polysperma, it should keep pace with any of the plant the crayfish eats. You could also try Java moss, as in my experience, they tend to mostly ignore it (though that can change from crayfish to crayfish).
I have a ten gallon tank with one blue crayfish who has a big hideout. If I added other hideouts like a few pieces of PVC, do you think adding a Mexican dwarf to the tank would be ok? Thanks!!
I might be fine, but you’re probably pressing your luck with a tank that small. If you could provide hiding spots that would be too small for the blue crayfish to enter, then you might be more successful. Also, I wouldn’t add it if the size difference is too extreme. A very large electric blue crayfish might simply hunt down a smaller one like the Mexican dwarf crayfish.
Hi Robert, I have two female mexican dwarf crayfish, How many times per day should I feed them? Currently I feed them twice a day a variation of hake, bottom pellets and blanched cucumber. I have them for 4 months now the one has molted twice the other one only once and is a lot smaller than its mate is this normal?Thank you Derek
Your current feeding schedule sounds good, as long as you don’t overfeed them. I’d recommend substituting zucchini for cucumber though, as it’s just as easy to prepare, but much healthier.
And you’ll always have some variance with molting like you have right now. Some molt faster than others, and part of it may be that the other crayfish is more dominant, thus getting access to more food. Also, one may be male and the other female, which could account for size differences. But as long as the molts are healthy, you don’t have anything to worry about.
I have two berried females with fertilized eggs at the same time and the eggs are around 10 days far and I can see eyes and a tiny tiny tail. However, I decided to isolate one of the crayfish by moving her to another tank and within 24 hours, she decided to drop all of her eggs.
The other female (which i left untouched) seems to have shed a significant number of her eggs too (~10 left?) from the 20+ she started with. Am I doing something wrong? I have a ton of hiding places for them in my tank (large rocks for my gravel) and a few large moss balls and 2 drift woods. Other than these two guys, I only have 2 cardinal tetras who have never really paid much attention to the crayfish.
The water parameters are also very good 0 ammonia 0 nitrite and like <20 nitrate and I do regular weekly water changes. How can I make sure my other female keeps her eggs!
The usually discard bad eggs. They may not have been fertilized, or they may have had some sort of fungus on them. Beyond that, I’m not sure. You could try to treat them with an anti fungus, but that doesn’t sound like it’s the problem here. And sometimes they seed to discard a lot of the eggs for no reasons, but you still end up with a few babies.
And was the new tank cycled? Even if it was, it can be stressful for a crayfish if you don’t acclimatize her to the water first, which may have caused the immediate egg shedding.
The eggs are for sure fertilized, they were dark and they are far along enough that I can already see the tail and head and eyes.
I moved one of them and that was when she dropped all of her eggs. I picked her up in the shell she was hiding in and then when she got out of the shell into the new tank, she dropped all of them… =(
The new tank was just water from the old tank.
It could just be a stress thing if they all appeared to be viable eggs. I wish I could pinpoint something, but sometimes they just do this their first couple of spawnings. Sorry I couldn’t be more help.
Both females just molted (1 day from each other)… I’m wondering if molting will cause crayfish to lose their eggs?
Most species of crayfish I’m aware of will delay molting until the hatchlings leave their body. This is especially noticeable in northern climates, where the spring molt is delayed for several weeks, while the non-breeding females and males molt much earlier. So, I don’t think it would have affected it.
I’m new to the hobby of crayfish I accidently removed his molted shell before he could eat it…oops I was not informed to keep it. Will he be OK it’s been a few days he seems fine but I’m worried. Also I gave him plenty of hiding places and he was totally active and never hid before and after molting and he really doesn’t choose to go into his hiding spots often, what’s up with that? Are shrimp pellets enough to get him the iodine he needs or should I add it to the water too? I also noticed the water isn’t all that cold not hot but just room temp should I try and make it cooler and how could I do that? I have a million questions because I really love this guy he’s a crack up with so much personality. I never would have guessed. I also put him with feeder goldfish which are disappearing pretty quick will he overeat and get sick? He’s got feeder fish, pellets, daphina, and I gave him a pea for veggies. I wanted the fish for some more life and movement in the tank I knew he could eat them but I bought 10 less than a week ago and I’m already down to 5. Once they’re gone can i/ should I buy more? I feel like I’m overdoing it I’m excited and want him to have it all but that might be bad.
It’s probably not too much of a problem, though you want to make sure to supplement his diet now. I’d probably add a few small pieces of cuttlebone for now, and maybe pick up an marine iodine supplement. Though you would only want to use it at half or quarter strength for now.
And if that many fish are going missing that quickly, you should definitely check the water quality. That many dead animals can foul the water quickly, and I would also check all of his hiding spots to see if he hid any of their carcasses. If the water is going bad, it might explain some of the problems.
I love crayfish they are the best I have two big ones and one little one. They are all in different tanks
I would never put them in the same tank. They eat very well. I got one from the pet 🏪 and the crayfish was so needing to eat. I give mine all kinds of food. Please do not give them the same food all the time. They need all different kinds of food they can eat. I would have more of them if I could but I can not three is more then enough for me at this time.
I bought my dwarf today from the local petstore, they said it was an Orange Lobster, when they told me it would only get 2inches I got sceptical on the lobster part. After doing some Research I found out it is actually a dwarf crayfish. However I noticed it only has one claw. Also I’m going out of town for a week I can’t find anything that says if it will eat a feeding tab. I know their diet is pretty much wide open however I don’t want it to starve while I’m gone if it won’t eat the tab. Any advise would be appreciated. Thanks
There’s no reason to suspect it wouldn’t eat a tab. While I’ve never fed them one personally, they are quite happy eating fish food, and a tablet isn’t all that different.
I would also probably give it a decent sized veggie to snack on as well if it’s in a moderately sized tank. If it’s in a small tank, I wouldn’t bother, since there’s too much chance of fouling the water.
Hi! My tank got ich and almost all of my fish died. I want to make sure there is no ich before repopulating – can a dwarf Mexican crayfish withstand the temporary higher water temps?
Did you medicate the tank at all? Ich medication is very deadly to crustaceans.
Can they be kept with Panther Crabs?
To be honest, I haven’t been able to get my hands on a panther crab yet, and I don’t know anyone who has kept them. I do know they will eat fish though, so I assume the crayfish would be in danger during moulting – and possible even under normal circumstances. Mexican dwarf crayfish are pretty docile, while panther crabs are somewhat aggressive. While I can’t say for sure, I would suspect they may not do well together.
Hi. We are new to fishtanks-3 weeks. Our dwarf Mex crayfish has disappeared. I saw it yesterday up near the top of the side filter on the netting we added for safety from filter suction. The crayfish being up at the top od the tank was unusual. Its usually scoothing around on the bottom. Our set up-3 gallon tank, with heater, bubbler and rainbow lights. We feed ‘bug bites tropical formula, salmon recipe and insect larvae one time per day to tank. Live plants in powder soil. 1 rock. Originally had a neon tetra, gudgeon (sp?), tetra, snail and crayfish. The gudgeon never seemed well (store said gisfeons are smart and curious)and was at bottom and slow. The gudgeon died within a week and the crayfish was eating him. Dont know if this is how gudgeon died. A week later, Found neon tetra floating on the top. This week, I saw crayfish on netting near filter-then he disappeared today. Snail was always at the top near filter-and now, after craufish disappeared- snail is on the side at bottom! Rock is not reallu cave like. Could crayfish crawl out? One other odd note, i saw a cricket near the fish tank last night while crayfish was still around.. Foul play? Appreciate any and all info and ideas. Thank you
It’s not unusual for crayfish to escape tanks -especially small ones. Search under everything in the room and you may find your crayfish. Also, search the tank, because if the crayfish is hiding, then it might be molting.
As for the tank, have you checked the water conditions lately? It sounds like the tank is crashing, or something else is wrong.
Thank you for your insight, Robert. We never found the crayfish — and did not know to check far and wide for him. Unless crayfish can last a week or so out of water…Well, he was a good friend.
As far as the water condition, I need to learn how to monitor the water — any recommendations? Thank you again!!
That’s too bad your crayfish is probably gone.
As for the water conditions, most pet stores will test samples for free. But if you want to do it on your own, you can buy testing strips of kits (kits work far better) to keep an eye on the water.
Hello, I want to ask something regarding the Dwarf Crayfish. Is it acceptable if I put 1 male with 4 female in Aquarium for breeding. Or I have to separate them and make it 1 male and 1 female only?
How big is the tank and what’s the setup like?
Are these ok to have with Cory Cats
I was wondering if they are bc i put a full sized one in my tank and all my fish started to disappear
It was just a crawdad that i bought
It is a community tank with heavy plants on one side
The good news is that you’re really open with your setup and water. If you want really small fish, you can’t go wrong with rummynose tetras or harlequin rasboras. How many corys do you have? I would probably add more to get a really nice school as well. If you’re looking for a bit larger, you could consider platies, black skirt tetras (one of my favorites), zebra danio (they will nip your guppies if you don’t have a school of at least 6). I hope this gives you some ideas.
If u have 2 African dwarf frogs can u get a dwarf Mexican crayfish
As long as there are plenty of hiding places for the crayfish it should work. But if it doesn’t have places to hide, it might be in trouble when it molts. The frogs might try to eat it.
Also – and this is unlikely – some Mexican dwarf crayfish are aggressive. It’s rare, but if this one is, it may try to attack the frog. Like I said, it’s rare, but I still wanted to warn you.
Mine i breed alot of Blue and Orange dwarf crayfish.. no any fish in tank just small shrimp and snails.. so they breed very fast.. they really love mud hides.
From 6pcs, after 6months i got 150pcs+
Hi, I am setting up a new 5 gallon for a dwarf crayfish. My question is; “What is the best substrate for them?” I have used several types over the years for my shrimp and planted tanks.
It all depends on what you’re doing with them. I try to avoid sand since crayfish can really make a mess with it. It’s a purely crayfish tank, then gravel, or large river stones work best. The river stones have the added benefit of making the tank easier to clean, which is great since crayfish are such messy eaters.
Which color of crayfish is the most active.
I have a majestic blue that hides out for a long period of time and when it does show itself, it might be out for 5 minutes then dissapears again. I have a newly acquired vanilla lobster that is out and about most of the time and very active. I’ve researched care for, but haven’t found out which color crayfish is most active.
In my experience, there is no one ‘active species’. A lot comes down to the individual crayfish, their environment, and their tankmates. I have found plenty of hiding places and fake plants make them feel more comfortable, which in turns makes them come out more. I’d try adding a few more caves and fake plants to see if it helps.
Can crayfish be in a tank with Khuli loaches and guppies? Was interested in getting one.
Unfortunately, those would both be bad choices for crayfish tankmates. The kuhli loaches inhabit the bottom and will almost certainly fall prey to the crayfish. While the guppies are slowly moving with long tails and may be caught by the crayfish as well. If you want crayfish tankmates, they need to be top dwelling and fast fish – and even those may still be eaten by the crayfish.
I am new to raising crayfish but I’m thoroughly enjoying it however I have a female who has numerous times breed with both of my males even though normally breeds with just her one big daddy LOL they are actually wild from a mudhole in a creek that had to be drained during my work …they are red and dark in color although I’ve seen them breeding numerous times I’ve never been able to find any eggs whatsoever on her belly any mucus sack anything that I researched about it and I’m wondering what could be the problem? why isn’t she carrying eggs when she is often breeding
.. and thus far I’ve had good luck because I also have a very small self cloning crayfish very small very dwarf size who just molted but has not ‘cloned’ and two of my wild red and brown crayfish have molted successfully I currently have a electric blue and orange also..I believe my blue is in the process of molting now.. he has built himself a barrier in the corner and I intend to keep a very good eye on him. I feed them minnows and algae Wafers and zucchini and pellets I keep the water clean as much as possible because I can’t stand the bad smell anyway
often changing the water sometimes more than once a day but the issue with my female not having eggs is starting to puzzle me. They have plenty of hiding places they seem to get along very well even hiding together in some of the cave I have made for them so I don’t know what the problem could be any thoughts? Thank you very much
My first thought is that daily water changes can be very hard on crayfish. How much water are you changing? Are you treating the water? Also, how large is the aquarium?
I see eggs in my crayfish but 2 days after the eggs is all gone inside the female crayfish, can you tell why did that happen? TIA
Most likely the eggs weren’t viable and they were consumed by the mother. How many other crayfish are in the tank with the female crayfish?
I used to have 4 dwarf crayfishes in my 120lt aquarium for just 2 months.
During that period they killed one molly, one guppy and one rasbora and they attacked to my pleco at least once.
I returned them to the petshop…
Don’t add them in a community aquarium!
I just caught my male crayfish pinning down my female one and thought he was killing her (cuz he ripped out one of her claws last week) so I interrupted and separated them with a poke. Is this going to give them ptsd and prevent mating in the future?
I don’t think crayfish are smart enough to experience anything like that. They’ll mate again when the chance arises.
Wow! This has been a great and helpful forum to read! I read your article before and after get my male and female dwarf Mexican crayfish. They are so fun.
I’m wondering first how often I should offer them food such as the sinking pellets, zucchini, algea wafers, and such. I have a bunch of coexisting shrimp and a snail as well, and they live in a Fluval Flex 15 gallon.
Also, if the female becomes pregnant is to hat when I can move the male to my other tank or should I do it now? Or do you think they ann in ready bred? She is so tiny. He has tried to get close but I don’t think she has let him. I have a shrimp but and she can get through it and hd can’t. I really want to experience the event of her carrying the babies and all though. But I want to be responsible as well as my other tank is 9 gallons and has a betta, 2 white cloud minnows, a neon tetra, and two corydoras that live each other so much. I can make a 5 gallon tank for him and cycle it pretty quickly with seasoned substrate I’m taking out of the 9 gallon. I also have two sponge filters in the back if the fluval (one fits in the back of the marineland 5 gallon he would go in. So it would be cycled really quick with beneficial bacteria.
Or do you think it’s okay to just leave them alone and have my sweet little tank I live and watch this natural process. I’m enjoying them so much. They are so cute and friendly. I’m just concerned that if she has babies will I be able to care for all of them and how many will actually mature in that tank? And How many shrimp and dwarf crays will coexist in there? And can I add any to my other tank if they multiply if there are plenty of places to hide?
I can see the aquariums from where I sit. I cannot have a larger aquarium. I just got the Fluval 15 gallon cycled and replaced the 5 gallon with it. So I’m loving watching all the shrimp and I am absolutely hooked on the sweet little Crawfish.
Thanks so much.
I thoroughly enjoyed reading the informative article before and after I got my cute little male and female dwarf crawfish. I love them already. They have quite the personalities!
I have them in a 15 gallon Fluval Flex with shrimp and snails. I made plenty of places for them to hide in case she gets pregnant and has babies.
My questions…
Ifshe does get pregnant how many babies should I expecting live and grow up and how many can live with the shrimp in the tank? I want to have a realistic expectation so I can be responsible to create the best environment. But I just got the fluval cycled (it replaced a 5 gallon so it was a big step for me) and got them in it. So getting another tank isn’t an option for me now.
I have another tank almost 9 gallons with a few shrimp, a betta, 2 corydoras that love each other’s much (I know they deserve a huge tank, and at least 5 others like them, but one is tiny and the other just a bit bigger and I’ve had them since the beginning of my aquarium hobby and they seem happy), a neon tetra, and 2 white cloud minnows. There’s a few great hiding places I there for my shrimp, so I think maybe a crayfish would be okay…or not?
Also just wondering how often I should offer the zucchini, pellets, algae wafers, etc… I don’t want to over feed but don’t want to underfed.
Thanks so much.
I witnessed my female CPO with black eggs under her tail. After awhile she climbed inside a piece of cholla wood and when she appeared there were no eggs or young. The male was seen eating her molt that has some unfertilized eggs on it. How soon will they be ready to mate again? Should I separate the female next time? They are in a 10 gallon by themselves with rocks with crevices this time.
