That is a great question!! Are they getting along? Shih I know you must love their look in your already great looking tank.
I really like Chromis School look. Before getting them I did my research. Asked around.
The one comment I got was "Over time you will be left with only one".
But I couldn't resist and got 8 Blue Green Chromis's (same size) about 8 month ago.
They went thru the pecking stage, establishing dominace order.
Then one died shortly, and there were 7. They swam nice as school for a long time.
One by one they killed each other off, by not allowing the weakest to eat. But remaining school stay together. One out each time.
I saved one since he swam weakly into net, and he is alone in another tank.
I now have 3 BIG Chromis's left. They don't school anymore.
There is an good Article about them in Coral Magazine VOL 13, No 2.
Says you need to get them in higher numbers, preferably 10-12 depending on tank size (to diffuse the aggression).
I want to increase the school to larger number, but LFS's don't carry big ones. Not sure it adding 10 small ones, to 3 big established ones is a good idea.
