Just found an Interuptus for sale on a website for $1140 US.
They are also being captive bred by a company in Hawaii, along with Resplendent angles. They had them listed for $900 US. Must have been the wholesale price.
Never seen (and probabily never will) a Peppermint Angel ( Centropyge boylei) for sale. I read an article on them a few years back that said they were selling in Japan for about the same price as a new car.
