简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 10-12; 臀棘 0; 臀鳍软条: 11 - 14. Diagnosis: It is distinguished from other species of the subgenus Chromaphyosemion by its blue anal fin with no submarginal red band, vs. species with a submarginal red band present, except for Aphyosemion poliaki, and very rare specimens of A. melanogaster and A. malumbresi (Ref. 119374). It differs from the latter species through a combination of the following features: flanks and venter yellow-orange with no red punctuation vs. flanks bronze and venter brown-orange with regular red dots, flanks yellow-green and venter yellow-green with a black zone and irregular lines of red dots, and flanks bluish-white and venter bluish with a black zone and regular red dots; blue iridescent scales on the ventral region close to the caudal peduncle vs. red scales or black scales; black alpha-shaped mark on the pre- and post-opercular region vs. no alpha-shaped mark, only a few red macules; anal fin blue with an orange portion on the basal region with no punctuation except black dots on basal and/or posterobasal portions vs. anal fin blue-green with many red dots, yellow-green with red dots, bluish-white with red dots (Ref. 119374).
This species lives in small, secondary rivers and small, forest streams, often with a sandy bottom, where it can be found along the riverbanks; it hides quickly in water plants or dead leaves (Ref. 119374).
