Synonyms[1]

Rasbora is a genus of fish in the family Danionidae.[1] They are native to freshwater habitats in South and Southeast Asia, as well as southeast China.[2] A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful.[3] They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.[2]

Several species are regularly kept in aquariums. As a common English name, "rasbora" is used for many species in the genus Rasbora, as well as several species in genera Brevibora, Boraras, Megarasbora, Metzia, Microdevario, Microrasbora, Rasboroides, Rasbosoma, Sawbwa, Trigonopoma and Trigonostigma.[4] Some of these related genera were included in the genus Rasbora in the past. In a 2007 analysis, Rasbora was found to not be a monophyletic assemblage. However Boraras and Trigonostigma were determined to be monophyletic.[5]
