Double Bar Chromis

(Chromis opercularis)

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 Double Bar Chromis are also known as the Double Bar Lightning Chromis. Not commonly seen in the aquarium trade. Juveniles and adults will have different coloring. The juveniles will be a magnificent blue and yellow color with a thin black stripe behinds its eye and a thicker black stripe further back on its body. The juveniles tail lobes are an elegant yellow with black tips and elongated. As the fish matures they become an alluring silver brown color. They can grow to a little over 6".

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