Teleostei (teleosts) > Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Nanochromis: Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); transvestitus: Specific name derived from the female's more intense coloration; the male is less conspicuous, a feature that is the reverse of many other cichlld species; reversed sexual dichromatism is however common and well-distributed among the chromidotilapines; females are more colorful than males in many of the genera related to Nanochromis (e.g. many Pelvicachromis species)(Ref. 52307)..

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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