Écologie
marin récifal; non migrateur; profondeur 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. 9626). Reported in the eastern Atlantic off Senegal (Ref. 10797).

Maturity: Lm 7.0  range ? - ? cm
Max length : 12.6 cm TL mâle / non sexé; (Ref. 9626)
Épines dorsales (Total): 12; Rayons mous dorsaux (Total): 15-16; Épines anales 2; Rayons mous anaux: 13 - 14
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).
