Red tailed sharks, like rainbow sharks, tend to be territorial and are intolerant of others of their own species. If more than one is kept, the weaker specimen will be constantly harassed. They need plenty of swimming room and mix well with large robust tank mates. They need fairly well-oxygenated conditions. The waters to which these fish are native are slightly acid to neutral, of moderate hardness, clear and swift flowing. They are quite adaptable to higher pH and hardness.
Plants are a large part of its diet, so be cautious when introducing them in a planted tank. A hood on the aquarium is also recommended, as the Black Shark is an accomplished jumper. Should be fed with flake food, freeze-dried bloodworms and tubifex, as well as vegetable-based foods.
