I almost got the Chromis, they were the same price, maybe I will. Acutally, my LFS doesn't take back fish. The other LFS does which is about 30 minutes away. I usually go there, but wasn't in the area today. The damsels will be agressive towards other fish, like gobies and such?
My skimmer has been taking out some very think milk stuff lately so that will be good. Hopefully with the water changes it will get even better.
