Black Axil Chromis

Chromis should be added to well established aquariums with plenty of room to swim. Plenty of rock work should be provided for resting or hiding. Chromis prefer a strong water current which in the wild provides them with a large supply of Zooplankton. Chromis readily accept most diets of meaty and algae based foods which should be fed multiple times daily to satisfy their grazing behavior. Chromis should be housed with other peaceful fish so they are not out competed for food. Chromis are generally reef safe but research each species carefully to ensure adequate habitat. Juveniles and adults may display color differences. Adults may also see color differences during courting and spawning, males tend to be larger than females.

The Black Axil Chromis is also known as the Black Fin Chromis or Blue Green Puller. This beautiful blue green Chromis is often confused with Chromis viridis. It is quite difficult to identify the difference between these two species. However, they can be differentiated by the color of their fins. The base of the pectoral fin of the Black Axil Chromis will be black with the Blue Green Chromis's appearing dusky from dark dots on the pectoral fin. Not often seen in the aquarium trade but quite lovely. They can grow to a little over 4.5".

We recommend a minimum aquarium size of 50 gallons or larger for this species.
