About Chromis dimidiata (Klunzinger, 1871)
Pycnochromis dimidiatus, commonly called the chocolatedip chromis or Red Sea half-and-half chromis, is a species of chromine damselfish in the genus Pycnochromis. This species is endemic to the Red Sea, where it lives on reefs at depths between 1 and 36 meters (3.3 to 118.1 feet). It was first described by Carl Benjamin Klunzinger in 1871. It resembles multiple other species in the genus Pycnochromis, including P. iomelas, P. fieldi (which was originally described for populations once classified as P. dimidiata found outside the Red Sea), P. hanui, P. margaritifer, and P. bami.
