Description

The slender catfish is a small three-barbeled catfish (Heptapteridae) from fresh water of the coastal region of southeastern Brazil. The species grows to about 12 cm and has a slender, elongate, brownish body with long barbels and an adipose fin. As a nocturnal bottom-dweller it shelters by day among roots and leaf litter of forest streams and hunts insect larvae and small invertebrates by night. The stout pectoral and dorsal spines can give a puncture wound when handled.
