Totally unrelated how did you manage to get the Scopus to play nice with two yellow tangs? Mine, the scopus, is a poo head. I love him though because it eats every form of algae but any other tang that looks like him, forget it.
Thanks! The Scopas and the two Yellows were the first three fish, and were added together as juveniles. They do flash their tail spines at each other occasionally, but nothing serious. Also they are very well fed.
