   For either a beginner or more advanced marine aquarium enthusiast, the Black-bar Chromis is a hardy, inexpensive and gorgeous fish!

   The Black-bar Chromis has such a delicate balance of color! A pronounced horizontal black stripe over it's posterior set against a yellowish to tan body. Then there is just a subtle touch of neon blue encircling the eye and etched along the bottom fins and the underside of the tail!

I like them very much but it is very incredible it is nowhere to find them in CHINA! along its coast do they inhabit naturally!

In a reef tank they are very active but seemingly not aggressive at all. They love to school from one corner to another, very attracting.
