Morphology | Morphometrics
Found in backwaters of rivers, small creeks, swamps, and lily lagoons, usually among thick aquatic vegetation over soft mud bottoms. Females lay about 30 eggs (2 millimeters in diameter) on the ceiling of overhanging rocks or crevices. These are guarded and fanned by males until hatching, which takes about 8 days (Ref. 44894).
