Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Mouthbrooders (Ref. 240). Distinct pairing during courtship and spawning (Ref. 205). Displays obligate monogamy where a one-to-one pair is established irrespective of resource abundance (Ref. 52884).

Estimates based on models
Preferred temperature (Ref.
123201): 26.6 - 29.3, mean 28.6 °C (based on 2597 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00680 - 0.03071), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.50 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).
Nutrients (Ref.
124155): Calcium = 248 [112, 510] mg/100g; Iron = 1.41 [0.72, 2.76] mg/100g; Protein = 18.5 [17.2, 19.9] %; Omega3 = 0.12 [0.05, 0.28] g/100g; Selenium = 33.4 [12.8, 81.1] μg/100g; VitaminA = 48.4 [11.6, 205.3] μg/100g; Zinc = 2.55 [1.49, 4.21] mg/100g (wet weight);
