Description

The Horseman's corydoras is a small armoured catfish (Callichthyidae) from fresh water of the western Amazon basin in Brazil. The species grows to about 5 cm and has a stocky body with two rows of overlapping bony plates and three pairs of barbels around an underslung mouth. The body has an orange-red tinge with a green flank patch. As a gregarious bottom-dweller it roots in groups through soft sand in search of worms, larvae and detritus and can take a gulp of air at the surface. The fish is harmless to humans and is popular in the aquarium trade.
