The only problem (not that big of a problem)is the CC substrate, these guys prefer a sand bottom in which to bury themselves. however you can keep them with crushed coral. as far as the inverts go, the radiant wrasse should be fine with them. (Of course there are always exceptions). Very small shrimp and feather dusters may likely become a meal, but the ones that you listed should be okay. Mysis shrimp, flake foods, formula one, and plankton will be good foods.
I definately recommend this fish for a peaceful tank. good luck...
