keeping a school of green chromis?

[sirrealism]

I just read this thread and am surprised that so many have had issues with aggression with these fish. Dont get me wrong they chase each other but in all the years I have kept them in groups I have never had them kill each other and I have had many over the years. Maybe I have just been lucky. Right now I have 4 in a 93 cube and they have been together for years. I have had them so long that one is close to 3" and has morphed into a different looking fish. This pic does not show the morph but it does show the size. The blue tang is well over 3"

I have lost the thread that I wanted to update.
After well over a year, my 3 Green Chromis have started to show aggression.
The larger two seem to be keeping the smaller one chased into it's hiding spot in my rockscape. So far there hasn't agression beyond the short chase but I'm thinking it will be only a matter of time before the fight starts

You can see in the photo that the smallest one has to hide.
It does get to come out to eat so far.

I have a friend with a 6' tank and her chromis do fine.

Also, I have read that each chromis wants its own little hidey hole to duck into. You need to aquascape with plenty of nice little holes.

Also, they like multiple small feedings.

I think the three things together ought to do the trick.
