I have a 150g that we just re-aquascaped bonsai style so there were no longer any established territories for any of the tank's inhabitants. I already had a pair of b/w occelaris, one of which is a cool misbar. Hubby and I took advantage of the tank being empty and added a pair of o/w occelaris as well, one of which was a semi-snowflake. We figured that as with tangs, if you add them at the same time, no problems. Well, no such luck. The b/w pair suddenly beat up the little snowflake after being fine in the tank for a couple of weeks. Poor thing didn't stand a chance and there was no way we could get him out, either. Had to let nature take its course. I wanted to replace him right away, after reading in Joyce Wilkerson's clownfish book that you can keep several occelaris in a tank together but only one pair will form, others will remains juveniles. Hubby said no more clowns! So I posted here, hoping someone would back me up but they said not to do it, that it wouldn't work. And they're right. The larger b/w has paired up with the female o/w and they've started picking on the little misbar b/w. We can't get him out so we're hoping that he'll have the good sense to stay on the opposite side of the tank. I totally understand how tempting it is to put more clowns in but in the end, not fair to the clowns themselves. *shrug*
