Anyone out there with (or had) a (marine) parrotfish?

I certainly do have a lot of corals for my parrot fish to chow down on and she does, but seems to prefer other foods like flakes, pellets, mysis etc. Now adays I think she just chomps on the odd coral to wear her teeth down. She has certainly not devoured any complete colonies during the past year. She is my personal coral pruner
