Biology

Inhabits deep coastal drop-offs (Ref. 8631, 48635). In Java Sea, taken only in dead reef areas in somewhat turbid water (Ref. 8926). Closely related species such as P. pleurotaenia and P. bimaculatus may spawn at the same time and produce accidental hybrids (Ref. 48635).

Diagnostic Description

Displays different or stronger color patterns when living together with similar looking species to enhance recognition by females which may lead to further speciation (Ref. 48635).Description: Characterized by juveniles with pinkish orange color with narrow magenta margins on yellow dorsal, anal and caudal fins; male with overall lavender pink color with irregular wavy band; female with orange spot on most scales of body; greatest depth of body 2.9-3.1 in SL; absence of fleshy protuberance at front of upper lip in males; slightly prolonged second and third dorsal fin spines; deeply emarginate caudal fin without filamentous tips (Ref 90102).
