Anything other than a bumblebee, or harlequin pretty much. I'd stay away from sauron shrimp as well. I've heard, but haven't been able to confirm that they will get agressive and go after all your other inverts. This is just hearsay as far as I'm concerned though.
Sexy, skunk cleaner, blood/fire cleaner, peppermint, coral banded, anemone, pistol, should all be fine.
