A blue and a naso would not be a issue if your tank is large enough.
And why does everyone have a yellow tang do they have awesome personality or what?
Have 3 of them. Very active energetic fish. Also very bright/colorful.
Tullsterx: Yes I have a convict. Does not show aggression towards anyone but no one messes with him either. When a something new is added to the tank it will protect it from getting bothered by other fish. Also coaches new fish out. Eats from hand and will let me pet it like a dog.
By far best personality of any fish I have.
I do not have a kole but none of the yellows have a problem with it. Here is a old pic of it when it was a "baby" Just added from QT
