Why does my cleaner shrimp run from fish?

[PowermanKW]

I bought a cleaner shrimp to help the health of my tank. Had it for a month or two. Already shed 3 times. Seems healthy. Eats well. When I was moving rock it jumped on my arm and went to town.

So... I have a new Hippo Tang that has some sort of parasite. I also had a Coral Beauty that seems to have fin rot. His fins are real tattered and getting worse slowly. Noticed it when I bought the tank a couple of months ago.

My Beauty presents to the shrimp, but it runs. All it does is hang out on it's power head. It comes down at feeding and at night. However, it won't clean the beauty. Also, my Beauty is the least aggressive, slowest moving fish in my tank. I have never seen it clean anything, doubt it's helping the Hippo Tang.

It did eat a shrimp right out of my hand once though???

Any help is most appreciated. I'm a newb.

I had a cleaner shrimp that acted the same way. it was very very active and liked to clean my hand, but would never even go near any of the fish.
