Description

Geay's rainbowfish is a colourful fish of the family Bedotiidae, endemic to Madagascar. The species grows to about 9 cm and has a slender, silvery body with a dark lateral stripe and, in males, handsomely red and black-edged tail and fin tips. It prefers well-shaded, quieter sections of small streams at altitude. As a surface and midwater hunter it feeds on insects, larvae and small zooplankton. Owing to deforestation, habitat loss and introduced species the wild populations have strongly declined, so the species is listed as Endangered (EN). It is popular in the aquarium and is harmless to humans.
