More on author: Ahl.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 4 - 65 m (Ref. 9710). Tropical
Western Indian Ocean: Red Sea and the Gulf of Aden.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 4858)
Found over coral and rubble areas, in pairs or in small groups. Found to depths of 65 m (Ref. 81209). Feed on coral polyps, gorgonians, algae, polychaete worms and small crustaceans. Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205). This attractive fish does well in aquarium surroundings and therefore highly prized by hobbyists (Ref. 4858).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Form pairs during breeding (Ref. 205). Monogamous mating is observed as obligate, genetic and social (Ref. 52884).

Estimates based on models
Preferred temperature (Ref.
123201): 23.6 - 29.4, mean 26.9 °C (based on 104 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.38 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (12 of 100).
Nutrients (Ref.
124155): Calcium = 116 [59, 180] mg/100g; Iron = 0.903 [0.532, 1.514] mg/100g; Protein = 18.6 [17.4, 19.7] %; Omega3 = 0.13 [0.08, 0.22] g/100g; Selenium = 38.5 [20.7, 72.8] μg/100g; VitaminA = 46.9 [13.2, 165.5] μg/100g; Zinc = 1.53 [1.03, 2.22] mg/100g (wet weight);
