Description

The Siamese algae eater is a cyprinid (Cyprinidae) from clear, flowing rivers and forest streams of Southeast Asia. The species grows to about 16 cm and has a slender, silver-brown body with a dark longitudinal stripe from snout to tail and an inferior mouth with horny lips with which it rasps algae from stones and wood. As a bottom-oriented grazer it eats aufwuchs, filamentous algae and detritus. The fish is harmless to humans and is prized as an aquarium algae-eater.
