I originally had 2 of them. The one that I added to the display (wasn't thinking at the time) got stuck to my 6101 and survived for only a week after that. They were originally barely 1" and the one I have now has grown considerably and is starting to get a nice brilliant blue. I will take some pictures tomorrow for those who are interested. He eats everything except the Nori sheets (trying to get him to eat them). So I've been feeding a lot of NLS pellets and Formula 1 flakes. The one that I have now was living in my fuge for a while before i put him into qt to grow him out. The qt is pretty bare right now, it consists of some base rock I just cured, a heater, and a mini filter.
Tim, you are right about getting small angels from the aussies. I just happened to come across an importer in Montreal that received a few.
