Color
A fish with a pale yellowish upper head and back that fades to lavender pink below, with bright yellow caudal-fin lobes, and a dark pink margin on the dorsal fin and lower edge of caudal fin. The body color of females is monochromatic, whereas males have a purplish second half of the body.
Etymology
Luzonichthys: named for Luzon Island, Philippines, type locality.
waitei: named in honor of “distinguished” Australian zoologist Edgar R. Waite (1866-1928), for his many contributions to ichthyology.
Original description: Mirolabrichthys waitei Fowler, 1931 - Type locality: Port Maricaban, Luzon Island, Philippines.
Distribution
Biology
Usually in groups on outer reef slopes. Most commonly occurs in shallow water and most likely seen by divers. Forms dense aggregations that feed on zooplankton. Aquarium fish. Capable of changing sex.
Similar species
Luzonichthys whitleyi (Smith, 1955) - Reported from New Caledonia. A small slender splitfin with bright yellow on the snout, top of the head and back, lavender pink elsewhere.
Luzonichthys williamsi (Randall & McCosker, 1992) - Reported from New Caledonia.
