| These fish are always active even at night. They school during the day and at night they separate into groups of two. I have 10 of these chromis and they get along with my clownfish, tangs, shrimps, and don't nip at my clams or corals. But they do like to play (chase) each other around my elephant ear coral, and they bring water movement to it. I highly recommend this fish to everybody, experienced and beginners.

| great reef tank fish adds color and plenty of movement to my tank. I traded a spiny box fish for 8 at the local fish store, much better for the reef.

| I have found out from my local fish mart that the best thing to do is buy them in odds! make sure because they are very agressive if bought separately. I think the perfect number is three because they are always moving around. And to my suprise i found out that once you buy a group there is always a leader, the one that gets bigger and gives the whole group character. A great beginner fish.

| My chromis fishes have very unique personalities. The larger green one seems to pick on the smaller blue one. The green chromis has gone to the point in which he's bitten the top part of the fin of the blue chromis. They also hide behind the coral whenever I walk by my tank. Ive seen chromis adults 8in long in my local petstore.

| I have found this fish to be a great schooling fish. It is a joy to see them swim together in one big mass.
