Etymology: Xanthichthys: Greek, xanthos = yellow + Greek, ichthys = fish (Ref. 45335). More on authors: Jordan & Gilbert.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 6 - 130 m (Ref. 89972). Subtropical; 35°N - 31°S
Western Pacific: southern Japan and the Ryukyu, Izu, Marcus, Wake and Hawaiian islands. Eastern Pacific: southern California, USA and the Pitcairn, Easter, Revillagigedo, Clipperton, and the Galapagos islands (Ref. 5227, 11482).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm NG male/unsexed; (Ref. 89467)
soft rays: 26 - 29. Males are straw-yellow with each scale outlined in black creating a crosshatched appearance, and a red tail with neon submarginal blue band. Females are also crosshatched, but with a slate gray to blue ground color and tail.
Found mainly around oceanic islands and near reefs along the continental coasts (Ref. 9276). Found in schools in seaward reefs above drop-offs (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on zooplanktons (Ref. 89972).
Males establish a territory for spawning and parental care but not for feeding (Ref. 116451). Only females tend the eggs but both parents keep guard (Ref. 116451).
