About Chromis atripes Fowler & Bean, 1928
Pycnochromis atripes, commonly known as the dark-fin chromis, is a diurnal species of damselfish in the genus Pycnochromis. Its scientific name is also cited as Chromis atripes Fowler & Bean, 1928. This species is distributed from the Western Pacific Ocean at Christmas Island, and from north-western Australia in the eastern Indian Ocean, east to Kiribati, north to southern Japan, and also occurs in Tonga. It lives on outer reefs and coral-rich outer reef slopes, and occurs either alone or in small groups near the seabed. It is oviparous; males of this species guard and aerate the eggs.
