Fin's Fish Guide

Description
Grasse's dwarf fish is an extremely small cyprinid-like fish (Kneriidae) from the fresh waters of Central Africa. The species grows to only about two centimetres and has a translucent body. Unlike many small bottom fishes it does not bury in the sand but lives in open water, where it forms schools; in the rainy season, when it spawns, it can be locally very abundant. It feeds on very small zooplankton. Owing to habitat loss the species is considered vulnerable. It is harmless to humans.
