Rasbora

A rasbora is a member of a group of small minnow-type fish in the family Cyprinidae (carps). Fish from genera such as Boraras, Microrasbora, Rasbora and Trigonostigma are commonly referred to as rasboras. The genus Microrasbora may be more closely related to danios than other genera in this group while the genera Boraras and Trignonstigma were split from Rasbora. Currently the genus Rasbora remains the largest one which can be found in Southeast Asia and Africa.

Most of the rasboras are small, up to 10 cm long. A number of species are regularly kept in aquariums; the most common of these is the harlequin rasbora (Trigonostigma heteromorpha).

In a 2007 analysis, Rasbora was found to not be a monophyletic assemblage; however, both Boraras and Trigonostigma were determined to be monophyletic.
