Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 15 - 18; Espinas anales: 0; Radios blandos anales: 15 - 17; Vértebra: 32. Diagnosis: Nothobranchius niassa belongs to the subgenus Adiniops, which has a preopercular red pattern, wide chevrons on side and a deep red caudal fin without any dark margin in males (Ref. 91043). It is distinguished from all other species of this subgenus by the unique combination of the following characters in males: dorsal fin rays 15-18, anal fin rays 15-17, light blue iris, light blue dorsal and anal fins with curved red stripes, and red pectoral fin (Ref. 91043).
Body shape (shape guide): fusiform / normal.
Found in pools of seasonal streams, less than 50cm deep, with no vegetation, and with leaf litter and gravel as bottom substrate; on type locality the water was light clay gray, slightly turbid with low conductivity (Ref. 91043).
