Will the blue and green chromis school together? How agressive are they..I know a lot of people try to get rid of damsels and I see them listed in the same catagory? Is a school of 10 too big?
I've never tried mixing the two types, but I suppose they might school together.
My chromis sometimes chase the other fish a little, but I've never seen them nip at the other fish. They are very aggressive eaters though... mine are pigs.
As far as a school of 10, that would entirely depend on how large a tank you have and how many other fish are in there.
