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]
