Many years ago I had one, well before I had any idea what I was doing. It was a great fish and must have been very hardy because I did so many things wrong and yet it stayed beautiful, fat, and healthy looking. I had it 5 years before it died because a fire in my stand resulted in a complete tank crash.
It did eat small feather dusters. I had many of the little red ones and they all were all eaten. Nice fish though, never touched any of my corals.
