生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in rivers, streams, swamps and lakes. Occurs along muddy shores and in papyrus swamps in Lake Victoria; also in ponds of rice schemes (Ref. 36900), side-arms of larger waters (Ref. 78218) and in mountainous streams (Ref. 27292). Mainly insectivorous (Ref. 248), a wide variety of insect larvae and crustaceans (Ref. 78218). Also small fish are taken (Ref. 27292). Might undertake mass migrations up rivers and streams, maybe to spawn (Ref. 27292).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.2   ±0.40 se; based on food items.
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
