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).
坚强地, 偏爱安静, 在较大的河的湖，沼泽与湿地或边缘区域与缓慢流动的溪流中的植物生长良好的水域。 吃包括昆虫，小的蜗牛与甲壳动物，藻类，硅藻，与碎屑的各式各样的小生物。 被 sharptooth 鲶鱼，虎鱼, largemouth 鲤科食用鱼 ( Serranochromis 种) 与鸟捕食。 产卵植物中夏天时。 (参考文献 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).
营养阶层 (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.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (K=1.40; tm=1; Fec=255; assuming multiple spawning per year).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
