lunar wrasse

Hi there, i have a 50 gallon saltwater talk with an adult female maroon clown in there. I have a 100 gallon i plan to set up in coming months and a buddy of mine wants to get rid of a smaller lunar wrasse. The wrasse is around 3 and a half inches big and the clown is massive at around 5 inches...

What is the growth rate on these guys? I have a 40 gallon breeder with an empty 125 that I'm going to set up in the future. However it will take a while until I finally move into my new house. I'm guessing a year at most.
