Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 25; depth range 0 - 70 m (Ref. 34291).   Tropical; 22°C - 26°C (Ref. 2060); 3°N - 5°S

Length at first maturity / Size / Weight / Age

Maturity: Lm 9.6, range 10 - 12 cm
Max length : 17.7 cm SL male/unsexed; (Ref. 34290)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7. 32-54 mandibular teeth. Maxillary barbels reaching almost to the origin of the pelvic fin in some specimens and to the tip of the humeral process in others. Outer mandibular barbels with slender branches, inner pair with shorter, but slender branches. Marbled yellowish-brown (marbling is extremely variable, some individuals uniformly brown) (Ref. 34290).

Biology     Glossary (e.g. epibenthic)

Inhabit lakes (Ref. 4967) but appears to be more common in rivers than in lakes (Ref. 34291). Feeds on mollusks and insects (Ref. 13624). Insects, particularly chironomid larvae and Povilla, are dominant in the diet (Ref. 34291). Oviparous (Ref. 205). Rarely grows to lengths greater than 15 cm SL (Ref. 34290).
