Rainbow sharks are renowned for their unique appearance and close resemblance with large ocean sharks. Though popular, they can be difficult to keep. This guide will run through everything you need to know about rainbow sharks, including housing, ideal water parameters, feeding, and breeding techniques.
These fish have a distinctive appearance: long, dark bodies, pointed snouts and a flat abdomen. Their fins are typically red/orange in color. When fully grown, rainbow sharks can reach 6 inches in length.
They’re highly-territorial fish and are prone to aggressive behaviors towards other, smaller fish. Generic breeds usually have dark blue/black abdomens with red/orange fins.
Male rainbow sharks usually appear slightly lighter in color than females, though their appearance is still quite similar. Since breeding rainbow sharks is really difficult, there aren’t many different varieties; the only alternative type known are albino variants.
These sharks have bright white abdomens with red fins and eyes. Albino breeds are extremely rare.
