Occurs in vegetated areas in shallow water, but also found in rivers and streams around the lake. Feeds on invertebrates, algae, plants, small fishes and plankton (Ref. 5595). Ovophilic, agamous (Ref. 52307) maternal mouthbrooder (Ref. 6307, 52307).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Female lays batches of eggs on a substratum which the male begins to inseminate. Female collects the eggs almost immediately after laying a batch and incubates eggs in her mouth for 12-14 days at 26°C, releasing the young after which. Parent guards the young for 5-7 days, keeping them into her mouth when approached by predators or divers.

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.41 se; based on food items.
Resilience (Ref. 120179
