fish suggestion needed

[yahutch]

I am looking for fish suggestions to aid in making some live rock safe for my dwarf seahorses . the fish will not be housed with them , I will move the rock after it has been cleaned . I need a sm-med sized fish that will eat bristle worms , flat worms , hydroids , and that kind of nasty stuff .it will also need to eat frozen foods . this fish will need to be reef safe as it will reside in my mixed frag tank (5 ft long 1ft deep ) . I have a really small ( quarter size )regal growing out in that tank as well .does not have to be pretty , just effective .what would you get ? and have you seen any local lately ?
thanks

You can get a six lined wrasse. I was going to suggest copperband butterfly but they aren't always reef safe.
