Just added mine to the tank, he's doing great. I let him clean my hand for about 3 minutes, he was willing to do that after being in the tank for maybe 10 minutes. Just now I saw him try to clean a damsel. The damsel is really tame, but wasn't sure about letting the shrimp clean him, it was pretty funny, especially since they are about the same size. I'm sure they'll be buds soon.
