Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory; depth range 1 - 15 m (Ref.
40395
), usually 1 - 4 m (Ref.
9626
). Tropical
Western Atlantic: Brazil. Some authors consider the population in Caribbean Sea as another species,
Pomacentrus dorsopunicans
(Ref.

Adults inhabit shallow, coral or rocky bottoms and sometimes near the shore in areas with little visibility (Ref.
9626
). Juveniles were collected from tide pools and on rocky
Lithothamnion
reefs; adults found up to 15 m depth (Ref.
40395
). A diurnal species, adults feed on benthic algae, polychaetes and harpacticoid copepods (Ref.
9626
); also consume hydroids and sponges and has been observed to feed on
Abudefduf saxatilis
eggs at night (Ref.
9626
). 16:21 SL/TL (Ref.
9626
). Oviparous, distinct pairing during breeding; eggs are demersal and adhere to the substrate; males guard and aerate the eggs (Ref.
205
).

Preferred temperature (Ref.

Trophic level (Ref.

): 3.3 ±0.23 se; based on food items.
Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
