No problem!
What I normally do is select whichever I believe to be inferior in comparison to the others and those are the ones I remove - ie choose the two best and leave them. I've always done this, even when buying the fish and had them pair up within a matter of days. I've never found it a necessity with these fish to allow them to select a mate from a group, but that might just be me.
If a pair is already bonded, keep them together, chances are they're the nicest fish anyway. If there is no formed pair then it's entirely up to you which female you leave with the healthy male.
HTH!
