Mixing Fairy Wrasses

[efish19]

I have a long fin fairy wrasse and am looking to add a red velvet fairy wrasse. My local fish store has two in stock one which is about the same size as what I have now and colorful, definitely a male. The other is a bit smaller and a little less colorful, maybe a sub dominant male or even a female. Which of the two would you think is the safer bet?

I'd get the current wrasse out a week before adding then add the more colorful wrasse from LFS then add long fin wrasse. Going from the aggression mine shows. (My tangs taught him how to flap lol)
