簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 12 - 13; 臀棘: 0; 臀鰭軟條: 13 - 15; 脊椎骨: 24 - 25. Diagnosis: This is a fairly large species of the subgenus Chromaphyosemion, larger than all its congeners with the exception of Aphyosemion riggenbachi, which has the most forward placed dorsal fin (Ref. 41203). It is a strictly blue phenotype with a unique red marking on the sides of the body with the exception of the gill lids, with two conspicuous, mood-dependent dark longitudinal bands, with a red dotted dorsal fin, a flamed caudal fin and an "undrawn" anal fin, except for a thin red submarginal and white marginal band, with longer trapezoidal vertical unpaired fins and a caudal fin with short extracts in the males; the female also shows the alpha-shaped mark, with striking, dark bandages and an anal fin without spots, but without a dark mesh pattern around the scales on the sides of the body (Ref. 41203).
Body shape (shape guide): fusiform / normal; Cross section: oval.
雄性是具有一個紅色的字母狀的符號的顯著的藍色在鰓蓋上面與後面。
This species is found in clear creeks under forest cover, usually over a sandy soil, in the coastal plain (Ref. 80395).
