Expect some squabbling, which can be really unnerving. I've got three small angels (though only one centropyge) in my 185. Each new addition got hazed. The last one, a Potter's, I was really worried about and came close to pulling him. Once everyone started ignoring him, he got comfortable and started harrassing my multibar. Again, I thought I would have to pull the Potter's. They seem to have worked it out now, though.
