Adults inhabit lagoons and coastal reefs, usually in silty areas (Ref. 4966). The true D. prosopotaenia ranges from Singapore to Sulawesi while the yellow-breasted variant ranges from Irian Jaya to eastern Australia and Vanuatu (Ref. 48636). May be found solitary or in groups (Ref. 90102). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699).

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 29.3, mean 28.6 °C (based on 2251 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00651 - 0.03363), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.18 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100). 🛈

Nutrients (Ref. 124155): Calcium = 82.7 [45.2, 136.7] mg/100g; Iron = 0.689 [0.421, 1.073] mg/100g; Protein = 19 [18, 20] %; Omega3 = 0.135 [0.086, 0.212] g/100g; Selenium = 19.4 [11.5, 35.3] μg/100g; VitaminA = 109 [36, 318] μg/100g; Zinc = 2.12 [1.51, 2.91] mg/100g (wet weight);
