Chromis dimidiata is a genus of fish in the family Pomacentridae.
Description
Anterior 2/3 of the body is dark brown to black; posterior 1/3 pearly white. Body depth 2.0-2.1 in SL. Dorsal spines (total): 12; Dorsal soft rays (total): 11 - 12; Analspines: 2; Analsoft rays: 12.
Distribution
Western Indian Ocean: restricted to the Red Sea. Populations in the Indian Ocean are now considered a separate species, C. fieldi, which has a more curved demarcation between white and black parts of the body (such that the white often covers more of the dorsal spines).
Habitat
Adults inhabit lagoon and seaward reefs. Abundant, in large aggregations over reef tops and upper edges of slopes. Usually seen solitary in reefs, staying close to the substrate in depths of about 10 m. Diurnal species. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
