Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 65 - 75; Espinhos anais: 0; Raios anais moles: 17 - 19. Diagnosis: dorsal fin greater than twice the length of anal fin; dorsal origin nearer tip of snout than caudal fin base; snout 2-2.5 times in head length; caudal peduncle less than 4 times in standard length (Ref. 52193).

Found in caves and muddy areas, also hides among weeds (Ref. 13337). Favours quiet deep water with a soft muddy bottom (Ref. 52193). Forms shoals (Ref. 13337, 52193). Feeds on weeds (Ref. 5595) and insects but may also feed on small fishes (Ref. 5595, 52193) and fish eggs (Ref. 52193), blood worms (Ref. 13337), small crustaceans and mollusks (Ref. 13337, 52193). Active mainly at night; breeds during the rainy season, moving upstream in rivers after flood spates have receded (Ref. 52193). Migrations appears to occur at irregular interval as this fish is not a powerful swimmer and would not be able to cope with very high water current (Ref. 13337). Females carry 10,000-70,000 eggs; can give a mild shock when caught (Ref. 7248, 52193).
