Etymology: Pseudanthias: Greek, pseudes = false + Greek, anthias = a fish, Sparus aurata (Ref. 45335).
More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 0 - 180 m (Ref. 9710), usually 0 - 25 m (Ref. 90102). Tropical; 22°C - 27°C (Ref. 27115); 30°N - 23°S
Pacific Ocean: Indonesia to Samoa, north to Ryukyu Islands, south to New Caledonia and the Rowley Shoals in the eastern Indian Ocean (Ref. 1602) and Christmas Island (Ref. 114977).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 10; Dorsal soft rays (total): 16 - 18; Anal spines: 3; Anal soft rays: 6 - 7. Highly variable in color and also in the size of the pale blotch (looks blue in natural light). Latter varied from being totally absent to an area almost half the body size, especially when showing nuptial colors. At the Rowley Shoals, off the north-western Australian coast, it only shows the blotch when nuptial (Ref. 48635).
Aggregations of this species occur a few meters above the edges of current-swept drop-offs (Ref. 4538). Females and males in separate aggregations or mixed sexes (Ref. 48635). Juveniles solitary and remain close to shelter (Ref. 37816). Seldom encountered in the aquarium trade (Ref. 1602).

Estimates based on models
Preferred temperature (Ref.
123201): 25.3 - 29, mean 27.9 °C (based on 620 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00618 - 0.02945), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
