Fun!
But I am curious : Assuming you found $800 lying in the street, would you really want that fish?
It is rare, sure, but only a few experts would know that. So minimal bragging rights.
And rare means it probably should have been left on the reef, not sold.
So perhaps a bit of guilt.
It is really not that different from a Carpenter's anyway.
In fact, I might argue some of the "cheap" flasher wrasse look nicer.
And the stress of an expensive/rare fish seems like a pain.
