Short description Morphology | Morphometrics

Dorsal soft rays (total): 11-13. This species is distinguished by the following set of characters: lateral line line scales 61-67; D 11-13; pectoral-fin rays 11-13; body depth 16.0-22.2% SL; head length 30.1-33.7% SL (Ref. 126777).

Biology     Glossary (e.g. epibenthic)

Lake Kalimpa’a, where the species was collected, is characterized by calm water with sandy and muddy substrate, the vegetation was dominated by the weed Phragmites karka (Cyperales: Poaceae) and reported depth is about 11 meters with and water temperature 22 °C with pH 5–6.5 and DO 13.9 Mg/L, when measured during daytime. Other species present in the lake were introduced African tilapia Oreochromis sp., the snakeskin gourami Trichopodus pectoralis, and a native eel Anguilla species. This species is a pelvic-brooder, where females carry an egg cluster until hatching (Ref. 126777).
