Etymology: Labropsis: Greek, labrax, -akos = a fish, Dicentrarchus labrax + Greek,opsis = appearance (Ref. 45335).
Eponymy: Dr Gerald Robert ‘Gerry’ Allen (d: 1942) is an American-born Australian ichthyologist. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 4 - 52 m (Ref. 2137). Tropical; 19°N - 12°S
Western Central Pacific: Indonesia, Philippines, New Guinea, Solomon Islands, Palau, and Marshall Islands.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 9; Dorsal soft rays (total): 10 - 11; Anal spines: 3; Anal soft rays: 9 - 10; Vertebrae: 25. Male differ from female in lacking the dark spot above origin of anal fin, the 1 or 2 narrow dark stripes anteriorly on body, and the dark spot anteriorly on the dorsal fin. Posterior caudal peduncle and fin white; upper and lower procurrent caudal rays usually 7. Preopercular margin free from corner to level of mouth; suborbital pores 7-9; preopercular pores 8-11.
Occurs in lagoon and seaward reefs, in areas with dense coral growth (Ref. 9710) and on steep slopes, solitary or in pairs (Ref. 90102). Probably feeds on coral polyps (Ref. 6023). Juveniles clean other fishes.

Estimates based on models
Preferred temperature (Ref.
123201): 27.3 - 29, mean 28.3 °C (based on 272 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.61 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).
