Morphologie | Morphométrie
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 13-16; Épines anales 0; Rayons mous anaux: 15 - 17; Vertèbres: 28 - 30. Diagnosis: It is distinguished from all congeners by the following unique combination of characters: males with about 30-50 dots on flank, each being lesser in diameter than the radius of the pupil, a proximal stripe on anal fin, pelvic fin reaching the genital papillae, dorsal fin tip reaching the caudal fin, females also with dots on flank; dorsal fin with 13-16 rays an27-29 scales in the median lateral series (Ref. 95020).
Found in temporary pools and swamps (Ref. 3788). A bottom spawner, with 1.5 months incubation (Ref. 27139). Difficult to maintain in aquarium (Ref. 27139).
