Need advise on the best way to catch a cleaner wrasse

[my2rotties]

I have a large cowfish in QT and he will be ready to come into the display in awhile. I cannot have a cleaner wrasse with a fish of this type. They have no scales and cannot be picked on and cleaned by the wrasse. I have time to get him out and he needs to come out so he does not stress out the cowfish with any picking.
