The rainbow shark is a species of Southeast Asian freshwater fish from the family Cyprinidae. It is also known as the ruby shark, red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark and whitetail sharkminnow. It is a popular, semi-aggressive aquarium fish. Unlike true sharks, which belong to the Chondrichthyeslineage, the rainbow shark is an actinopterygiian . One of the more colorful cyprinids, this fish can be distinguished at a glance from its red-tailed relative because all its fins are reddish in color. Red-Fin Sharks require an aquarium incorporating suitable retreats, such as a clay flowerpot set in the substrate, and some floating plants at the surface to create dappled lighting. These fish are more tolerant of their own kind than Red Tails, so they can be bred more easily. The females swell with eggs, laying up to 4,000 at a single spawning. The resulting young are soon large enough to feed on brine shrimp. The white form of the Red-Fin Shark is now widely available. It retains the reddish fin markings, but the body is mostly whitish or transparent. ORIGINS Southeast Asia, being restricted to northern parts of Thailand. #redfiinedshark #auqrium #fish
