Fin's Fish Guide
The Longdorsal catfish (Chrysichthys longidorsalis) is a freshwater fish of the family Claroteidae that grows up to 31 cm.
Description
The longdorsal catfish is an African catfish of the family Claroteidae from West Africa. The species grows to about 31 cm and has a streamlined body with barbels around the mouth, an adipose fin and stout fin spines; the name refers to the relatively long dorsal-fin base. As a bottom dweller it searches rivers for small invertebrates, molluscs, crustaceans and plant matter. Owing to a restricted range and threats to its habitat the species is listed as Vulnerable (VU). Like other catfishes the sharp pectoral and dorsal spines can give painful puncture wounds, so careful handling is advised.
