Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8 - 9; Vertebrae: 26. This species is distinguished from its congenes by the following set of characters: predorsal area with cycloid scales, 3-15 predorsal scales on predorsal midline; vertebrae 10 + 16 = 26; males with low first dorsal fin, not extending posteriorly to origin of second dorsal fin when adpressed; third spine of first dorsal fin longest; lateral and ventral sides of belly with ctenoid and small cycloid scales, respectively; absence of posterior oculoscapular canal and preopercular canal; sensory-papillae rows on cheek arranged longitudinally, with no transverse rows; first dorsal fin with a single longitudinal row of vertically elongate dark markings; no dark large circle or quadrangle markings (spots or blotches) at anterior part of first dorsal fin; the lower half of caudal fin without reddish orange coloration; caudal fin have some vertical rows of dark dots in both sexes (Ref. 119678).
This species is reported to occur in shallow freshwater areas with mud bottoms and aquatic vegetation, such as ponds, marshes, reservoirs, canals, creeks of middle or lower reaches of rivers. A non-diadromous species, restricted in non- or slow-flowing freshwater habitats throughout the life cycle (Ref, 119678).
