Characteristics
They are native to the freshwater rivers and streams of Southeast Asia, but many species are brightly coloured, and are available as aquarium fish worldwide. A number of the species, only recently discovered in remote inland areas of Laos and Myanmar, do not yet have scientific names.
They generally do not live for more than about two to three years, and are probably annual fish in the wild, although the larger species may live for up to five years.
In the wild, these fish consume various small, aquatic insects, crustaceans, worms, as well as, in the case of fry, plankton.
