Fin's Fish Guide
The Shortfin antenna catfish (Chasmocranus brevior) is a freshwater fish of the family Heptapteridae that grows up to 8 cm.
Description
The shortfin antenna catfish is a small South American catfish of the antenna catfish family (Heptapteridae) from the Guianas. The species grows to only about 8 cm and has an elongate body with long barbels, to which the family name refers. It is relatively rare, probably owing to its highly specialised habitat in brooks and small rivers. As a nocturnal bottom searcher it probes the bottom with its sensitive barbels for insect larvae and small invertebrates. The stout pectoral spines can prick, so handle the fish with care. Owing to its small size the species has no fishery value.
