Why does it matter if someone else would pay it. The real question is would YOU buy it? If there is a fish out there that I want, I don't care what the price is, most of the time I am going to buy it. It all comes down to you and how much you want that fish.
Having said that no, I wouldn't pay that for a red devil, WC or not. I would much rather just save that money for Crenicichla...
