The Atlantic gets pretty a) large and b) not so pretty as adults according to what I've read. Your choice, so I'm not going to knock it. I have a Tomini, and he is beautiful. Not passive towards the female clown, but pretty much great with everyone else. I'm going towards either a kole or clown tang to complete my tangs. Want a sohal, but too aggressive. I'm going to use my female clown as chum if she goes after my povona coral one more time...
Going with a pair of genicanthus angels; waiting on Rich to find me a pair. Maybe watanabe, maybe another breed.
