features

Limnotilapia dardennii becomes a maximum of 26 cm long. Most of the specimens in the lake are 10 to 15 cm in length. In fish of the same age, the males are larger. The color is silvery to olive green, often with a bluish sheen in adult males. Above the midline of the body there are six to eight dark transverse bands that can completely disappear during the reproductive time. Four more transverse bands lie on the top of the head, one of which goes through the eye. The fins are silver-gray, the pectoral fins yellow with a reddish upper edge. The reddish anal fin of the males has a few yellow egg spots.

Way of life

Limnotilapia dardennii lives sea-wide to a depth of 30 m above rock and sand soils. It feeds mainly on thread algae and aquatic plants and also ingests worms and other invertebrates as well as fish spawn. Its breeding season extends from March to May. Limnotilapia dardennii is a mouthbrooder that shows high intraspecific aggression. Spawning occurs near large mounds of sand that the males pile up. The maximum number of eggs is around 100. When leaving the mother's mouth, the fry are around 19 to 20 mm long.

Danger

In the Red List of the IUCN of the status of the species is given as safely (Least Concern).
