More Info

Distribution	Endemic to southeastern Queensland, off Coolum to east of Cape Moreton.
Features	Dorsal fin X,16; Anal fin III,7; Pectoral fin 18-20; Pelvic fin I,5; Caudal fin - principal rays 9+8, branched rays 7+6, upper procurrent rays 8-10. lower procurrent rays 9-10, total caudal rays 34-36; Lateral-line scales 40-44; circumpeduncular scales 27-28; Gill rakers 10-12 + 26-27=36-39; Branchiostegal rays 7; Vertebrae 10+16.
Colour	Male (from a photograph): head and body orange, becoming yellow ventrally on body and pale yellow on head; a broad pink oblique band extending from behind eye and occiput to anterior body, edged ventrally by bright pink to silvery pink stripe extending from midposterior edge of eye to upper part of pectoral base; second bright pink to silvery pink stripe extending from first infraorbital to lower part of pectoral base; area between pink stripes orange-yellow; iris bright yellow, edged with bright pink to dark purple; broad pink band on head and body breaking into mostly horizontal vermiculate lines, which cover most of ventral and posterior body including caudal peduncle; spinous portion of dorsal fin bright yellow, anterior three spines mostly bright red to bright purple-pink distally, pink becoming confined to distal tips of more posterior spines; membrane between anterior spines each with a small purple-pink spot basally, these becoming elongate streaks on more posterior spines; anal fin and soft portion of dorsal fin bright yellow, narrowly bright pink distally, with variously sized bright pink spots or streaks along each ray; caudal fin bright yellow, bright pink-purple broadly on tips and narrowly on edges of fin lobes, the basal part of fin with bright pink spots and short streaks along each fin ray; pectoral fins deep pink basally, the remainder of fins pinkish hyaline. Colour of females in life is unknown.
Feeding	Presumably aggregates to feed on plankton in the water column well above the sea floor.
Similar Species	Differs from other anthiadines in having the following combination of characters: dorsal rays X,16; pectoral rays 18-20; lateral-line scales 40-44; greatest body depth 35.9-38.3% SL (2.6-2.8 in SL); predorsal formula 0/0+0/1+1; no auxiliary scales on body; third dorsal spine longest; caudal fin lunate with filamentous extensions; males with pink mostly horizontal vermiculate lines on the ventral and posterior body and distal tips of caudal fin broadly pink-purple.
Etymology	The specific name paralourgus is from the Greek para (= beside, near) and halourgos (= made from the sea), in reference to the distinctive purple-tipped caudal fin lobes. Halourgus is a purple dye obtained from certain marine molluscs.
