I've heard of various angelfish going from anywhere from $500-$5,000, but this one takes the cake; the Peppermint angelfish, which, as the stories go, has sold for as much as $10,000.
Tizzo,
I've seen Goldflakes that look just as nice as the one in the pic you posted at a LFS near me for $199 on sale (normally $249). That price is almost low enough for me to justify buying one!
