I have a 90 gallon with 3 green chromis. I wanted to add 2 more to make it 5 because i heard they do alot better in schools of 5 or more. They are very skittish and i heard that people that used to have 3 had the same problem and then they added 2 more and the school acted completely different. My problem is i don't want to make my bioload to much. I change 10 gallons a week for a water change and have a 20 gallon sump overflow setup. I have 95 lbs. of live rock and have about a 3 inch sandbed. For tankmates i have 2 tru perc clownfish, flame angel, purplefish, royal gramma, yellow watchman goby, algae blenny and a foxface for a total of 11 fish. Would i be ok adding 2 more chromis or no?
i have 11 fish in a 90 is 2 more to much?

It seems no matter how many Chromis I have in my tank, I always end up with 3...lol. I started with 5 and 2 died. In another tank, I started with 4 and 1 died , so I purchased 2 more and they died. It would seem my tanks only want 3 Chromis. Now I have 3 Chromis that are doing well and have been in there for a long time...lol. I'm not adding any more. I do agree though that most say they do better in groups of 5 or more. I've also heard it's best to keep them in odd numbers. Not sure why though.

I had 6 one died. My 5 seem to be happy.
