Etymology: Pseudanthias: Greek, pseudes = false + Greek, anthias = a fish, Sparus aurata (Ref. 45335). More on author: Herre.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 18 m (Ref. 30874), usually 1 - 15 m (Ref. 27115). Tropical; 22°C - 28°C (Ref. 27115); 36°N - 29°S, 91°E - 155°W
Pacific Ocean: Christmas Island in the eastern Indian Ocean to the Line Islands, north to the Yaeyama Islands, south to the Great Barrier Reef, Fiji and Samoa. Replaced by Pseudanthias ignitus in the Indian Ocean (Ref. 37816).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.5 cm TL male/unsexed; (Ref. 2334)
soft rays: 7 - 8. Male displays a bright red dorsal fin. Ventral fins greatly extended. Female orange with yellowish tail and a pink line from the tip of the snout angling down, passing through the lower part of the eye (Ref. 48635).
Found at the upper-edge of steep outer reef slopes (Ref. 9710), with moderate currents (Ref. 48635). Occurs in large aggregations (Ref. 37816), of mixed sexes when feeding in currents sweeping the reef (Ref. 48635).

Preferred temperature (Ref. 115969
): 24.7 - 28.5, mean 27.4 °C (based on 923 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00398 - 0.02292), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
