The Tiger Barb (Puntius tetrazona), also known as the Sumatra Barb, is a small minnow native to Sumatra, Borneo, Thailand and parts of Malaysia. It has also been reported in numerous other areas of Southeast Asia, but at this time it hasn’t been confirmed outside of its native range.
In the wild, they are mainly found in the shallows of slow flowing streams, but can also be found in small bodies of water and swamp lakes. Because of their wide array of habitats, they are highly adaptable to different types of water in the home aquarium, and can adapt quite readily to harder water.
The tiger barb stays relatively small in the home aquarium, with adults growing to a maximum of 3 inches (7.5 cm), with 2 inches (5cm) being more common. On average they will live for 5-6 years if well cared for, and are generally a very hardy fish.
The first thing that you should know about Tiger barbs is that they are mean fish. Not the usual “nip an occasional fin” mean, but more the “will take your fishes lunch money, and yours too if you’re not careful” type of mean.
While that is a bit of exaggeration, it is incredibly important for someone buying these fish to realize that they are not a good community fish. In the past, many stores would sell these stunning fish to people hoping to put them in a community fish tank, and it would result in a disaster. This is becoming less common, as most stores are labeling tiger barbs as non-community fish, but you still hear stories about tiger barbs nipping fish to pieces in community fish tanks.
The best option for tiger barbs, is to house them in a species only fish tank. The aquarium should be at least 20 gallons, with the usual tank size rule applying – the bigger the tank is to start with, the better the fish will do over the long run. Larger tanks have more stable water parameters, and are actually far easier to care for than smaller ones.
If you would still like to take a chance with tiger barbs in a community thank, the best choices for tank mates are bottom dwelling fish that will generally escape their notice. This includes several species of catfish (not corydoras though), plecos, and clown loaches. Keep in mind that even these species can suffer at the hands of tiger barbs, and may have to be moved if they suffer excessive nipping.
There have also been some aquarists who have reported success with smaller cichlids, like convicts cichlids and Bolivian rams. But just remember, being placed with cichlids can end up being fatal to the tiger barbs, especially if the convicts start mating or become overly aggressive.
When it comes to choosing a filter for tiger barbs, the best choice is usually a hang-on-back filter. These will keep the water crystal clear, and maintain excellent water quality, but you should be careful not to over filter the aquarium. Tiger barbs prefer slow moving water, and any hang-on-back filter should either have reduced flow, or should not exceed the recommended tank size listed on the filter.
I would strongly recommend choosing an Aquaclear Power Filter for a tiger barb 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.
Tiger barbs are omnivores in the wild, and eat small crustaceans, insects, algae and plant matter. Because of this, they will eat nearly anything offered to them in the home aquarium, and their diet should be made up of a high quality flake food. They should also occasionally be offered live food, frozen foods and vegetables. One of the best prepared foods on the market, is Hikari Micro Wafers and I have used it with great success for my tiger barbs in the past.
Live food is usually superior to frozen foods, and has the added benefit of triggering the “hunting” response in fish. But when you can’t obtain live foods, there are many frozen foods that you can feed to tiger barbs. Some of their favorites are frozen bloodworms, blackworms, daphina, and brine shrimp.
Tiger barbs should also occasionally be fed vegetables, with blanched zucchini medallions and shelled peas being their favorites. If you don’t have the patience to prepare vegetables for your fish every few days, these can be replaced with spirulina pellets. A word of warning – many of the so-called spirulina pellets sold in fish stores have little, if any spirulina in them. Always read the label to make sure that the first ingredient is spirulina, and not something like fish meal.
The tiger barb is relatively easy to breed, and the only requirements are ensuring there is enough space for their courting rituals, and that live plants are provided (having a male and female helps too). It is also important to use a sponge filter in the aquarium, as a hang-on-back filter will suck numberless fry up to rather unpleasant deaths.
If you are planning to breed tiger barbs, the first thing that you have to do is ensure that you at least 6-7 of the fish. They should be placed in at least a 20 gallon long tank, with a 29 gallon being preferable. The tank should be well planted with live plants, with some aquarists stating that bunches of Cabomba work best.
Once you are ready to start breeding, the males should be removed from the tank. The males can be identified by their larger size, and the females will have more plump bodies. After a few days, they can be reintroduced to the main tank, which will usually trigger spawning.
During spawning, the males will chase the female until they begin to release the eggs. As the females release the eggs, the males will release their sperm into the egg stream. After the spawning is done, both the males and the females should be removed from the tank, as they will quite happily munch on the eggs that the females just laid.
If you want to increase the number of eggs that survive, you can use a similar trick to what is used during zebra danio breeding. The bottom of the breeding tank can be lined with river rocks, or marbles, which allows most of the eggs to falling through the spaces, becoming unreachable by the hungry parents.
After the eggs have hatched, the fry will cling to plants or the side of the aquarium for up to five days. They will then become free swimming, and can be feed with baby brine shrimp or commercially available fry food. As they grow, they can also be feed with finely ground fish food flakes.
