Description

The black madtom is a small catfish of the madtom family (Ictaluridae) from the south-eastern United States. The species grows to about 15 cm and has a stocky, dark body with barbels and an adipose fin joined to the tail fin. It lives near vegetation in moderate to fast-flowing, clear water over gravel and stones. As a nocturnal bottom searcher it feeds on insect larvae and small invertebrates. Madtoms have a venom gland at the pectoral spines; a sting gives a painful, burning wound, similar to a wasp sting. Therefore handle the fish with care.
