Description

The glass headstander is a characin (Characidae) from northern South America. The species grows to about 15 cm and has a deep, strongly arched, semi-transparent body through which internal parts are visible. It lives in still and slow-flowing waters of the Amazon and Orinoco basins, often among water plants. Striking is its oblique, head-down swimming posture, characteristic of headstanders. As a small predator it hunts insects, small crustaceans and small fishes. The species is popular in the aquarium hobby and is harmless to humans.
