I had my Moorish idol for over a year before I sold the tank, eating nothing but standard frozen foods. I believe the idols from Hawaii are suppose to be much better in captivity than those from other places like Indo.
I've also had a variety of sps picking fish, the only time you run into major problems is when they target a single colony as appose to spreading it out, which will likely happen once or twice. If you'll be devastated with a loss or two best to save yourself the grief and give it up or make a new home for him
