For the first time ever we could import this pretty barb from Thailand. At first we thought the fish would belong to the species Opsarius ornatus, but after they has settled all of our fish showed a clearly marked caudal spot, which is typical for O. bernatziki, but lacking in B. ornatus. Another very similar species from Thailand, O. signicaudus, also has a well marked caudal spot, but here it extends on the caudal fin. Some scientists do not see Opsarius as a separate genus, but include all species mentioned here under Barilius.
O. bernatziki can grow to a length of more than 10 cm, but usually stays much smaller (7-8 cm). Regarding the aquarium biology Opsarius can be best compared with Devario. However, Opsarius love a stronger current. So one should keep Opsarius species in a tank that reflects a biotope as it can be found in a brook a small river. All Opsarius are peaceful schooling fish. Male of O. bernatziki can be recognized by the bigger head and larger fins.
