upgrading from a 55 gal to a 125 gal. I already have a yellow tang but want to get another tang as well, along with a couple other fish. My concern is getting my yellow tang to get along with new fish. I was told to add new fish to tank when i swap tanks. and I've also been told not to add new fish right away after swap. So my question is when is a good time to add some new fish to new tank? And any recommendations on some good fish to add to reef tank with yellow tang, 6 line wrasse and two clowns that I already own
