Sicklefin Barb Puntioplites falcifer

The Sicklefin Barb, also Sickle-fin Barb, is native to the Mekong River basin in Thailand, Laos, Cambodia and Vietnam.

A large barb growing to 40cm long, it prefers slow moving water and migrates in schools. The "Sickle" name is after the shape of its long dorsal fin.

A small African fish, Enteromius haasianus, is called the Sickle Barb and sometimes (erroneously?) the Sicklefin Barb.
