Predominant food is the lake-fly in its larval aquatic stages (Ref. 246). Also feeds on plants; maternal mouthbrooder that does not pair-bond (Ref. 52307). Max. length of 27.5 cm presumed to be TL.

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Female mouth-brooder; breeding occurs during the rainy seasons and the young, a favorite prey for the tiger-fish, keep closer inshore among Eleocharis reed and other vegetation (Ref. 246). Young fish still attached to the yolk sac can be found in the mouth of a parent which is at the verge of spawning again (Ref. 52961). The species breeds during a single spawning period toward the end of the rainy season (Ref. 2774). At highwater, the fish move from the lake to their breeding grounds in adjacent swamps to spawn (Ref. 52346).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00986 - 0.03683), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.40 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tm=2-3; K=0.4).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Prijsklasse (Ref. 80766): Unknown.
