Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 10 - 13; Anale stekels: 0; Anale zachte stralen: 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).
Body shape (shape guide): fusiform / normal.
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).
