Kole Tang died?

Very true, but I would not consider those "aggressive". and with the light stocking in a 75, unless these two clowns had been there by themselves for an extended period of time, they would not be aggressive enough to lead to the death of a tang. It will also depend on the size of the fish as well. I had a pair of mated GSM clowns and the female, while mean to me when i had my hand in teh tank, never bothered another fish in the tank including any new additions. this was in my old 75.
