Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 4 - 5; Anal soft rays: 9 - 10; Vertebrae: 31 - 33. Differs from all congeners by its unique color pattern with scattered small white spots over the sides of the body and caudal fin with dark vertical bars. Can be further distinguished by the following combination of characters : third nuchal plate broad, with short lateral projection, post-Weberian vertebrae alternatingly ribbed and unribbed; caudal-fin lobes of equal length in mature females, upper lobe more elongated in mature males; and 31-33 post-Weberian vertebrae (Ref. 79512).
Found in semi-lotic environments. Some individuals were observed hidden within marginal vegetation or found inside crevices of submersed trunks. Reaches sexual maturity above 4.81 cm SL (Ref. 79512).
