What is your definition of "most expensive"? I would change that to "Most amount of money spent on a fish" ;
To me, most expensive means how much you pay for it and how much joy you get out of that. For example, I got a pink carnation coral for $40. Everybody seeing that coral was like "wow that is so beautiful" . It lasted me 40 days. That is like $1/day, so not very cheap but not so expensive.
Having said that, the most expensive fish would be a wild caught flame angel. I bought it for $32 at a lfs. After acclimating, I dropped it in. I saw it swimming for a few second and poof.... it went behind the rocks. Never saw it again. That was like $32 "gone in 60 seconds"
