Short description
Morphology | Morphometrics
Dorsal
soft rays
(total): 12;
Anal
soft rays: 8. Distinguished by its unique color pattern: young (2-2.5 cm SL) with 5-8 dark brown blotches, usually longitudinally elongated along lateral line and 6-8 saddles along dorsal mid-line, while adults the saddles extend downward and superficial pigments are superimposed to the former pattern, forming a marmorated pattern; large hammer-shaped suborbital flap in males (its depth about half eye diameter); and thickened first branched pectoral ray in males (Ref. 39226).
Occurs in stream with slow current and with depth never more than 30 cm during the dry season. Also found in shallow riffles over pebbles up to 5 cm in diameter, with clear water and moderate current. A female measuring 3.12 cm SL contained ripe ovulae about 0.7 mm in diameter (Ref. 39226).
