Fin's Fish Guide
The Emerald cory (Corydoras splendens) is a freshwater fish of the family Callichthyidae that grows up to 10 cm.
Description
The Emerald cory is an armoured dwarf catfish (Callichthyidae) from clear streams and blackwater creeks of the Amazon basin in South America. The species grows to about 5 cm and has a stocky body with two rows of overlapping bony plates, short barbels and an inferior mouth. As a peaceful, social bottom-dweller it roots through sand in small groups searching for insect larvae, small worms and detritus; sometimes it darts to the surface to gulp air. The dorsal and pectoral spines are mildly venomous and can give a painful prick when handled.
