ime, pairing maroon clowns is fairly difficult. they are just mean to any new tank mate. there are ways to get her used to it tho. if you get one half her size and young enough to still be a male, it will likely stay the male since the one in the tank will be larger. float the bag, acclimate in the bag, and when he is fully acclimated, use a breeder box to float him in. if she doesnt attack him while in the breeder box, you might be ok. even when you 1st put him in, shes likely to attack, just make sure that it doesnt get too nasty. keep a careful eye. does she have an anemone? if so she will be most aggressive near it, trying to keep him out. moving it might help a bit. rearranging rockwork might help too. good luck!!
