Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10 - 13; Anal spines: 0; Anal soft rays: 12 - 15. Diagnosis: This species differs from all other species in the Aphyosemion alpha group through combination of following features: head orange, flanks beige, ventral region orange vs. never the same colour pattern, orange anal fin with no punctuation vs. blue-orange, purplish-blue or orange with punctuation (Ref. 119374). it is distinguished from all other species of the subgenus Chromaphyosemion by an alpha-shaped drawing in pre- and post-opercular region vs. no alpha-shaped drawing, only some red macules (Ref. 119374).

Biology     Glossary (e.g. epibenthic)

This species lives only in very small forest streams and water holes, often with a bottom consisting of roots and dead leaves, where it can be very abundant (Ref. 119374).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
