Etymology: Chromidotilapia: Greek, chromis = a fish, perhaps a perch + Bechuana, African native thiape = fish (Ref. 45335); nana: Named in reference to the relatively small adult sixe of this species when compared with congeners (Ref. 50577).

Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 10-11; Anal spines: 3; Anal soft rays: 8 - 9. Diagnosis: 15-17 rakers on first gill arch; 2 large rounded to slightly elongated spots on flanks usually visible, sometimes with 1-2 small dark spots between the large ones; lachrymal depth greater than 22% SL (Ref. 81260). Usually a single row of teeth in both jaws (Ref. 50577, 81260).

Monogamous, pair bonding, ovophilic, biparental mouthbrooder (Ref. 81260).

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

In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00709 - 0.03231), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
