Description

The eyespot rasbora is a very small cyprinid from Southeast Asia, occurring on the Malay Peninsula and in Indonesia. It grows to only about 2 cm and has a slender, translucent silvery body with a striking green-glinting upper edge of the eye and a dark spot on the dorsal fin, from which it takes its name. It lives in schools in soft, slightly acidic blackwater in forests and swamps and feeds on worms, small crustaceans and insects. The eggs are scattered freely in shallow water. Owing to habitat loss the species is listed as Endangered (EN) on the IUCN Red List.
