Question about compatibility with wrasse

[Yates273]

I have a Christmas wrasse and was wondering if I can add a yellow/purple wrasse to the tank. Tank is 120 gallons with plenty of sand. Will they fight
This is the guy I want

This is the Christmas wrasse I have

I would say fighting is probable since they’re both of the Halichoeres genus

There's really only way one to know...

I have 7 or so, different wrasse in my 190g tank - different leopards, coris, tamarin, fairy - and they for the most part, get along.

If tanks big enough, generally...theres enough room for each fish.
