The Rainbow Shark, also known as the Ruby Shark or Red-Finned Shark, is great for the semi-aggressive community aquarium, as long as they are the sole shark and the other tankmates are of similar size. The Rainbow Shark is a beautifully colored fish which is a dark gray to black with red fins.
It requires a large aquarium with driftwood, rocks, and spots of dense vegetation. This shark may set up territories around the aquarium. The Rainbow Shark will become very aggressive towards its own species.
Unfortunately, the breeding habits of the Rainbow Shark have not been documented.
An omnivore, the Rainbow Shark is not a particularly finicky eater. Flake food, freeze-dried bloodworms and tubifex, as well as vegetable-based foods should be fed.
