Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 50.5 cm FL mâle / non sexé; (Ref. 35835)
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 11-12; Épines anales 0; Rayons mous anaux: 8. Anterior barbels very thick and dark, length less than 5.5 times in head length, less than 2 times in gape height, longer than eye diameter; oral gape inferior; dorsal head profile irregular, convex caudally and with a 'bump' caused by premaxillaries.
Over muddy, sandy and rocky substrates all over the lake, preferably in water deeper than 6 m. Feeds mainly on insect larvae, small mollusks, and detritus.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00201 - 0.00949), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
