Teleostei (teleosts) > Perciformes/Serranoidei (Groupers) > Anthiadidae (Fairy basslets or Streamer basses)
Etymology: Xenanthias: Although Regan (1908) did not specific the allusion of Xenanthias, the name is probably the combination of ξένος (xénos, meaning strange or foreign), and anthias, possibly an indication to a strange anthias.
Eponymy: Pierre Fourmanoir (1924–2007) was a French ichthyologist who mainly worked in New Caledonia for the Paris Museum’s ichthyology laboratory. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 16 - 18; Anal spines: 3; Anal soft rays: 7. This species is distinguished from its congeners by the following set of characters: no teeth on palatines; dorsal segmented rays usually 16-18 (rarely 20); fourth or fifth dorsal spine longest; pectoral rays 12-13, all unbranched; predorsal scales extend anteriorly only to vertical through mid-pupil; lateral line complete or interrupted, with 15-26 + 0-4 tubed scales. Colouration: a large black spot on the middle portion of dorsal fin, one near the end of the dorsal fin, one over the base of the last four anal rays, and one mid-ventrally on the abdomen in front of the anus (Ref. 123579).
Body shape (shape guide): fusiform / normal.

Biology     Glossary (e.g. epibenthic)

Inhabits coral reefs in lagoons and exposed areas (Ref. 8944). Deep-dwelling fishes. Feeds on small fishes and crustaceans (Ref. 37816). Solitary in crevices (Ref 90102).
