Longitudinal scale count 30-31; snout length 33.4-34.6% HL; maxilla reaching below pupil; mouth slightly prognathous; longest soft rays of dorsal and anal fins reaching well beyond base of caudal; scaleless opercular spot small; scaleless caudal rim on the suboperculum; scales on interoperculum in a single row; postorbital scale column mixed; gill rakers on upper part of ceratobranchial anvil-shaped, trifid on epibranchial; one inner tooth row in the lower jaw extending nearly as far posteriorly as outer row; caudal peduncle length 14.4-15.8% SL; and outer-row teeth in lower jaw 36-44 (Ref. 52072).

Biologi     Ordlista (t.ex. epibenthic)

Inhabits shallow inshore areas close to vegetation (Ref. 4983). Lake Victoria populations are largely omnivorous, larval insects and small crustaceans predominate in the diet (Ref. 558).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00703 - 0.03260), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.45 se; Based on food items.
Resiliens (Ref. 69278):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
