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 4 out of 5 by from Fun Addition We have a 29 gallon tank and added a rainbow shark. I am not sure if we got lucky or if they are truly not as aggressive as lead to believe, but I have yet to see ours picking on other fish or chasing them. Ours sticks mostly to the bottom, although sometimes he swims mid-level. The biggest thing is that they really do like to hide. We have an artificial tree root in our tank and could not figure out where our shark was disappearing to until we got a flashlight and shined it in the hole in the root and there he was swimming around inside it! I knew they liked to hide, but I just wish he came out a bit more, however it is fun when we do see him out and about!

Rated 4 out of 5 by from Great fish!!! This is a awsome fish. Totally recommend this fish. Can get aggressive when sized at 3-3.5 inches doesn't always get along with Cory catfish. But will never badly hurt another fish.Have had mine for 2-3 months and I love it, totally recommend it!!!!!

Rated 5 out of 5 by from My all time favorite fish! this fish is a boss. literary. when my tiger barbs pick on my snail this fish comes along and makes them back off. it is territorial. as in it likes to pick spots to rest and kick back. and as someone else mentioned does not harm any fish. i for sure recommend this fish. i was watching tanked though and they made this aquarium for a kid that looked like a tv. they put a lot of rainbow fish in there. if they fight those that boy may not be to happy later. perhaps the aggressiveness will even out. another problem with that tank though is that it was way to small for those fish. poor job on tanked i have to say. please be smart with this fish if not all. it is quite incredible if you can come to appreciate them.

Rated 5 out of 5 by from Love this guy This fish is easily the favorite of my tank(I named him swimmy for some reason), he is a little shy, but he's getting less and less each day. Its fun to watch this guy, he is a little territorial of his alligator skull decoration, but he's really a beautiful fish.

Rated 5 out of 5 by from awesome fish i have one of these in my community tank. he has not harmed a single fish...even the neon and glowfin tetras. on occassion he will pretend he will go after them, but truth be told he is just to lazy. ironically he has moved in with my pleco and they have become the best of friends. always just a short swim away from each other. i see Fin (as my children have named him) all threw out the day. he is very active in my tank and seems to enjoy swimming in and out of the hiding places i have created. he is also a camera hog! ever time he sees you near the tank he is just posing for pictures and loves the attention. he is a teddy bear in my tank. wish i could take him out and hug him :D

Rated 5 out of 5 by from great little shark i wanted to add a shark to my tank, and decided to go with the rainbow. He's a dark color with red fins. he is best friends with by black ghost knife and angelicus loach. The three are still babies and can't wait to watch them grow together. they all get along well in my 60 gal semi aggressive tank. i know sharks don't get along well w their own kind, so im glad that he has his buddies to swim around with!

Rated 5 out of 5 by from Awesome Fish I have had my Rainbow Shark for a few months now and I love him! He was a little aggressive for the first week or so but after that he has calmed down and swims freely through the tank, when he isn't hiding in his treasure chest. I love watching him swim upside down while eating stuff off my plants. I highly recommend this fish!
