Nate: The purple went crazy over the yellows for about 2-3 hours then started schooling with them. He does not pay them any attention now, nor does he swim with them. I have no aggression whatsoever. (I am surprised also)
Philly since you asked for my opinion.....Putting the clown in your tank was a bad decision. Your tank is not large enough for it. On top of that they are known to be really aggressive and will not tolerate another tang being added after them. I would return/sell the clown and get a yellow or a purple (not both) and a convict, kole, or blue. The 2 I would personally pick is a purple and a convict. Make the purple the last addition if not adding together. My convict is my bud. He comes to the surface and lets me "pet" him.
