Fish prices are crazy...
I was working as a "jobber", selling fish to LFS in the late 80's and early 90's.
I've seen it all... from Resplendent Angels which, btw... were less than $100 at one time to Wrought Iron Butterflies which were around $300
Some fish are astronomically priced today which were relatively cheap back in the day, but some fish have come waaaay down in price.
My first Asfur Angel I purchased for my personal collection at $400 wholesale. Much cheaper nowadays...
Oh and re: Clarion Angels... they used to be widely available and cheap. And... I didn't ever do it, BUT I heard of some people who would go down to Guaymas/San Carlos (wasn't me) and collected their own Clarions... CAUTION: Nowadays it will get you a million years in a Mexican Prison so don't DO IT.
