Description

Johnels's catfish is an African catfish of the family Claroteidae from West Africa. The species grows to about 33 cm and has a streamlined, silvery-grey to brownish body with barbels around the mouth, an adipose fin and stout fin spines. As a bottom dweller it searches rivers for small invertebrates, molluscs, crustaceans, small fishes and plant matter. Like other catfishes the sharp pectoral and dorsal spines can give painful puncture wounds, so careful handling is advised. Chrysichthys catfishes are of local fishery importance. The species is safe to eat.
