Despite their name and its connotations, sharks are extremely peaceful (except for red-tailed sharks) and live best in a community aquarium with fish of the same disposition. In fact, they are not really sharks and actually belong to the minnow family. It is their upright dorsal fin that gives them a shark-like appearance.

While most fish tend to stay at a certain level of the aquarium, you will see your shark swimming at the bottom, middle and top of your tank. They are omnivores, which means they eat both plant and animal matter, including prepared foods, small live foods and certain vegetables. Sharks are active swimmers and need a large tank that is long rather than tall. A good rule of thumb is one gallon of water for every one inch of full-grown fish.

Learn about the Rainbow Shark

Common Name
Rainbow Shark

Scientific Name
Labeo erythrurus



Very territorial with all fish. Does not tolerate members of its own kind.

Thailand: Decorate with live plants and plenty of rocks and driftwood for staking territories. Rainbow Sharks will stake a couple of territories at the same time.

Additional Comments
Juveniles need a lot of vegetation in their diet to promote proper growth and coloration. Without a proper diet their colors fade and their growth is stunted.

Rated 5 out of 5 by from Cool fish that is a low simmer So I got this one due to petsmart not having any red tailed sharks, which turns out that this guy is quite fun to have as well and looks beautiful in my tank. He tends to stay low to the ground (bottom feeder) however will swim around sometimes as well and is fairly active. If you are looking for one of the freshwater sharks to put into your tank, this one is quite fun to have.

Rated 4 out of 5 by from Rainbow sharks So i got a 20 gallon with 2 Rainbows 3 tetras and a Picus catfish (all Juvies) and they seem to all co-exist and in fact the 2 rainbow sharks are always together and get along quite well.

Rated 5 out of 5 by from Best shark like fish EVER! Overall, this fish is amazing. It looks great in my 55 gallon aquarium and hasn't given my other fish any trouble at all (Black Skirt Tetras, Blue Wag Platy, Otocinclus). I have 3 rock caves in my tank that my Rainbow Shark loves to hide in. This fish is also very peaceful. The picture on PetSmart's website is quite different from what the shark looks like in real life. I took some pictures of MY Rainbow Shark so you can see what they really look like.

Rated 5 out of 5 by from Cool fish These fish are a nice addition to a community tank. Some forums on fish keeping will tell you that they do not do well with catfish but mine is always trying to be near my cory catfish and is very gentle with them. He hates swordtails however and chases them around the tank. I think they have a lot of personality and when not hiding in their caves, they are fun to watch. Just make sure to only get one shark! The body is also blacker than it is blue like the picture above shows.

Are they aggressive towards other sharks(bala sharks) and other bottom feeders(corydoras, pleco)?

Asked by: Juan3774
Yes I had a bad experience when I had balas with the shark. He would always chase them and it got a point where the balas weren’t as active and looked very stressed. Do not recommend with balas
