Hardy, prefers quiet, well-vegetated waters in lakes, swamps, and marshes or marginal areas of larger rivers and slow-flowing streams (Ref. 7248, 52193). In shallow, inshore areas of Lake Victoria especially where bottom is sandy (Ref. 4903). Bottom feeder (Ref. 12526), it feeds on a wide variety of small organisms including insects, small snails and crustaceans, algae, diatoms, and detritus (Ref. 7248, 52193). Eaten by large predators like the sharptooth catfish, tigerfish, largemouth breams (Serranochromis species) and birds (Ref. 7248, 52193). Spawns amongst vegetation during summer (Ref. 7248, 52193), in river and streams during rainy season in Lake Victoria basin (Ref. 4903).
堅強地, 偏愛安靜, 在較大的河的湖，沼澤與濕地或邊緣區域與緩慢流動的溪流中的植物生長良好的水域。 吃包括昆蟲，小的蝸牛與甲殼動物，藻類，矽藻，與碎屑的各式各樣的小生物。 被 sharptooth 鯰魚，虎魚, largemouth 鯉科食用魚 ( Serranochromis 種) 與鳥捕食。 產卵植物中夏天時。 (參考文獻 7248)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00731 - 0.01887), b=3.01 (2.88 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.9 ±0.33 se; based on food items.
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (K=1.40; tm=1; Fec=255; assuming multiple spawning per year).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 391 [232, 744] mg/100g; Iron = 2.67 [1.66, 4.28] mg/100g; Protein = 17.4 [16.5, 18.3] %; Omega3 = 0.649 [0.249, 1.696] g/100g; Selenium = 98.5 [38.1, 260.6] μg/100g; VitaminA = 51.9 [22.0, 122.3] μg/100g; Zinc = 2.7 [1.9, 3.9] mg/100g (wet weight);
