(Fairy basslets or Streamer basses)
Etymology: Pseudanthias: Greek, pseudes = false + Greek, anthias = a fish, Sparus aurata (Ref. 45335).
More on author: Smith.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 20 - 100 m (Ref. 90102), usually 40 - 54 m (Ref. 9710). Tropical
Indo-West Pacific: East Africa, Maldives and Indonesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 8631)
soft rays: 7 - 8. Displays different or stronger color patterns when living together with similar looking species to enhance recognition by females which may lead to further speciation (Ref. 48635).
Inhabits deep coastal drop-offs (Ref. 8631, 48635). In Java Sea, taken only in dead reef areas in somewhat turbid water (Ref. 8926). Closely related species such as P. pleurotaenia and P. bimaculatus may spawn at the same time and produce accidental hybrids (Ref. 48635).

Estimates based on models
Preferred temperature (Ref. 123201
): 25.6 - 28.4, mean 27.4 °C (based on 264 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00548 - 0.02760), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±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.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
