The tinfoil barb is a fish of the freshwater Cyprinidae family, alongside carp and true minnows. It has silver or gold scales, red fins and a forked tail. The dorsal fin is tipped in black. An adult tinfoil barb can grow up to 35 centimeters in length.
Tinfoil barbs are found in Southeast Asia in freshwater rivers and streams.They have a neutral buoyancy, allowing them to float. These fish are mainly herbivorous; they occasionally eat insects, smaller fish, crustaceans and worms, however. They migrate back to their spawning ground to lay their eggs. Female tinfoil barbs have a lifespan of 20 years and can produce thousands of eggs each time they spawn. Tinfoil barbs travel in schools to confuse and hide from predators.
