Sundadanio

Sundadanio axelrodi is a miniature cyprinid from Borneo, where it inhabits black water streams and pools associated with forest peat swamps. Originally described as Rasbora axelrodi, it is the only member of its genus. Several colour forms exist depending on locality, normally labelled 'red', 'green' or 'blue', and they are best not mixed. Very peaceful but timid, it does best alone or with similarly sized species, in a group of at least 20-30.
