Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 11 - 14; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 12 - 15. Diagnosis: This species differs from all other species in the Aphyosemion alpha group through a combination of following features: head with very intense reddish colour, flanks bluish-orange, ventral region orange vs. never same colour pattern (Ref. 119374). It is distinguished from all other species of the subgenus Chromaphyosemion by an alpha-shaped mark on pre- and post-opercular region vs. no alpha-shaped mark, only some red macules (Ref. 119374).
This species was found in 3 to 5 metre wide rivers with fast running water, and sandy bottoms with no aquatic vegetation; they were hidden in tree roots along the riverbanks, or under dead leaves at the mouth of small secondary brooks, but they were not found in the small brooks themselves (Ref. 119374).
