Description

The dwarf hatchetfish is a tiny characin (Gasteropelecidae) from fresh water of the western Amazon basin in South America. The species grows to only about 2 cm and has a strongly compressed body with a deeply keeled, hatchet-shaped chest and large pectoral fins. It lives just below the surface and can briefly 'fly' out of the water with its pectoral fins to escape danger; it eats small insects from the water surface. The fish is harmless to humans.
