Description
Heptapterus mustelinus is a slender, nocturnal catfish native to the Paraná River basin in South America. It possesses long barbels and a mottled brown coloration, allowing it to camouflage effectively in its natural habitat of flowing waters with ample cover. This predatory species feeds on insects, crustaceans, and small fish.
