The Tinfoil Barb (Barbonymus Schwanenfeldii) is a tropical Southeast Asian freshwater fish. Originating in the Mekong and Chao Phraya basins of Thailand, Sumatra, Borneo, and the Malayan Peninsula, the Tinfoil Barb is found in rivers, streames, canals, ditches, and flooded fields.
It is distinguishable from other species of the genus in having a red dorsal fin with a black blotch at the tip, red pectoral, pelvic, and anal fins, red caudal fin with a white margin and a black submarginal stripe along each lobe, and 8 scale rows between dorsal fin origin and lateral line. Large individual fish are silvery or golden yellow while alive with its dorsal fin red and its caudal fin orange or blood red. Tinfoil Barbs can grow up to 14 inches long and live for up to 10 years.
Tinfoil Barbs reproduce by egg scattering of several thousand eggs per spawning. They are not often bred in captivity due to their large size.
