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
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.
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.
