I have a Scarus quoyi that I got from Blue Zoo. They had mislabeled it as a Princess parrott which is a Caribbean species while Quoy's is from the Indo-Pacific. I've had my Quoy's for more than 7 months and it's doing great. This species IS reef safe IME. I have a 180 gallon reef with SPS, LPS, leathers and clams and it has bothered nothing. It scrapes coralline algae from the rocks but makes no noticeable impact on the amount coralline cover. It also eats everything I feed including various frozen, pellets, flakes, mysis, nori, cyclopeeze, etc. It is peaceful and bothers none of my other fish. It was initially shy but pretty soon was out and about constantly and has great presence and is always begging. The colors are outstanding. My specimen is about 4.5 inches and has not grown much. My understanding is that they are one of the smaller parrotfish species. Non-fish friends/family always comment on it and recognize it as a parrotfish. Great fish!! Hard to find but worth it for a larger reef.
I got my trio after less than a month of waiting from one of the regular L.A. wholesalers, so your LFS should be able to get one. I was more worried about getting sent the wrong species, and being stuck with a fish that gets 3 feet.
