Oh no of course not. The africans are in my 135. (Notice very different backgrounds) The O's are in a 120 right now.
(I sometimes forget that for some reason only I know what I have in my tanks...)
Anyways the O's have some SA/CA with them, with plenty of filters and water parameters right for them. (Obviously the Africans have added salts etc and different diets.)
And thanks for the positive feed back everyone.
