Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 5 - 6; Raios dorsais moles (total) : 11 - 14; Espinhos anais: 1; Raios anais moles: 19 - 23. This species can be diagnosed by the following combination of characters: V-VI-I,11-14 dorsal-fin rays; I,19-23 anal-fin rays; 13-16 (usually 14) pectoral-fin rays; 35-36 scales on lateral line, 16-19 predorsal scales; 16-22 (usually > 20) cheek scales; 15-19 total gill rakers on first arch; greatest body depth of adult male 33.9 % SL; color in life generally shades of blue green to blue with metallic reflections and indication of darker blue mid-lateral stripe, most prominent on caudal peduncle where edged below with relatively broad white stripe; in situ color pattern composed of brilliant golden reflections especially conspicuous on each side of midlateral region on side of body and caudal peduncle; and reddish to yellow highlights on dorsal, anal, and caudal fins (Ref. 110723).
Body shape (shape guide): fusiform / normal.
Occupies habitat considered among the most scenic freshwater environments found at the Aru Islands, consisting of small, rainforest brooks with quiet pools interspersed with cascades to 3-4 m high. The habitat has excellent water clarity and stream channels composed of relatively smooth limestone with minimal aquatic vegetation, but abundant shelter for fishes in the form of log snags (Ref. 110723).
