I'm starting to stock my 125 gal tank, and began with 2 ocellaris clowns. Ideally my wife and I would like to complete our stock list with the three tangs mentioned in the title above - is it doable if the only other fish in the tank are the 2 clowns, a royal gramma, a midas blenny, a six-line wrasse, and (maybe) a flame angel? The yellow and purple, both being zebrasoma, may show aggression toward each other, but would adding all three at the same time mitigate that?
