Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 12 - 13; Spine anali: 0; Raggi anali molli: 16 - 17; Vertebre: 29 - 30. Diagnosis: Scriptaphyosemion wieseae is distinguished from its congeners by a unique combination of male and female coloration characters (Ref. 91031). Males have a blue body color, red dots on side forming irregular, interrupted red stripes, especially on caudal peduncle a more reticulated pattern, unpaired and pelvic fins centre blue with a narrow blue margin and a broad red submargin, on anal and dorsal fin a small number of basal red blotches, centre of caudal fin with some red blotches, pectoral transparent to orange with a blue margin; females with a dark brown midlateral stripe, interrupted on caudal peduncle, body on lower half of side and ventrally orange vs. a mainly red lateral body color in male S. cauveti (Ref. 91031).
Present in small rivers and a large rice swamp (Ref. 91031).
