Actinopterygii (ray-finned fishes) > Perciformes

Etymology: Pseudojuloides: Greek, pseudes = false + Greek, iouis = a fish without identification, perhaps some of genus Coris cited by Plinius + Greek, oides = similar to (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 61 m (Ref. 1602), usually 21 - ? m (Ref. 1602). Tropical; 33°N - 32°S
Indo-Pacific: East Africa to the Hawaiian, Society, and Austral islands, north to the Izu Islands, south to Lord Howe Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.3 cm TL male/unsexed; (Ref. 4392)
soft rays: 12;
Vertebrae: 15. Body color and pigmentation of males and females differ; geographic variation exists. In life, males olive green dorsally, bluish ventrally with double colored stripe (bright blue and yellow) on body. 8-11 small median predorsal scales; 5-8 suborbital pores from below anterior edge to midposterior level of orbit; 10-13 pores along free margin of opercle; 3 pores in front of anterior nostril. Caudal fins of some individuals slightly double emarginate. The primary phase of P. cerasinus is a salmon pink with yellowish fins (Ref. 1602). Juveniles collected in Sydney and reared to adults in an aquarium were observed to change from pink to the male pattern in about one week (Ref. 48636).
Occurs in clear lagoon and seaward reefs; common over coral rubble with algal clumps or in areas dominated with live coral (Ref. 1602). Rarely seen at depths less than 21 m (Ref. 9710). Benthopelagic (Ref. 58302). Population from Western Indian Ocean may be a different undescribed species (Ref. 90102).
