^^^What R1ant04 said. No females, that almost always ends up as multiple males and doesn't end well. Wrasses don't pair up and those genera almost always turn to male in our aquariums.
I'd add the Wetmorella genus and the Pseudocheilinops genus as well.
I would also add that if you choose a Pseudocheilinus wrasse it should be your only wrasse. That whole genus most often dosen't tolerate other wrasses even in good size tanks.
