Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 8 - ? cm
Max length : 28.0 cm SL male/unsexed; (Ref. 4967); 33.3 cm (female)

Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 10-12; Anal spines: 3; Anal soft rays: 8 - 11; Vertebrae: 30 - 32. Diagnosis: preorbital bone narrow (Ref. 2) and scaly, with 4 pores (Ref. 2, 4967). Upper profile of head nearly horizontal, concave in specimens 130mm and over; caudal peduncle long, dorsal and anal fins do not reach its posterior end when adpressed (Ref. 2).

Biology     Glossary (e.g. epibenthic)

Inhabits lakes; grows to only about 13 cm in the more saline lakes Eyasi and Manyara, but attains a bigger size under less saline conditions (Ref. 4967, 54836). Microphagous (Ref. 54840). Mouthbrooder (Ref. 2).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Breeding cycle of about 7 weeks; there is evidence of biparental mouthbrooding (Ref. 2).

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=0.01622 (0.00707 - 0.03721), b=3.02 (2.82 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
