Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7 - 8; Radios blandos dorsales (total) : 8; Espinas anales: 1; Radios blandos anales: 8 - 9; Vértebra: 26. This is distinguished from its congeners by the following set of characters: scales on predorsal area small cycloid, 8-17 scales on predorsal midline; pectoral-fin rays 20-23; longitudinal scales 28-35; vertebrae 10 + 16 = 26; males with a low first dorsal fin, not extending posteriorly to origin of second dorsal fi n when adpressed; third spine of the first dorsal fin longest; posterior oculoscapular canal is usually absent; preopercular canal usually present with two terminal pores; sensory-papillae rows on cheek arranged longitudinally, with no transverse rows; anterior part of first dorsal fin with no dark large circle or quadrangle dusky markings (spotsor blotches); absence of yellow or orange markings on caudal-fin base when alive or freshly-collected; caudal fin of males with some dark vertical lines, females with some dark vertical lines or rows of dots; lower half of caudal fin in males reddish orange when alive or freshly-collected (Ref. 119678).
Cross section: oval.
Occurs 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 its life cycle (Ref. 119678).
