Excellent Algae Eating Fish! The rainbow shark is a species of Southeast Asian freshwater fish from the family Cyprinidae. AKA ruby shark, red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark and whitetail sharkminnow.
These are a very popular, semi-aggressive aquarium fish best to keep in groups.
This species will do well in most larger, well-maintained tanks if plenty of hiding places are provided and should not harm softer-leaved plants. however we highly recommend keeping it in a set-up designed to resemble a flowing river with a substrate of variably-sized rocks, gravel and some large water-worn rocks. The tank can be furnished with driftwood branches.
Like many other fish that hail from running waters it is quite intolerant to the accumulation of organic wastes and requires spotless water at all times in order to thrive. It also does best if there is a high level of dissolved oxygen and a decent level of water movement in the tank so a powerful external filter or two should be added to the set-up.
