OMG, please don't put the fish in boiling water, its really miserable, use ice water instead. Don't behead either, i'm sure the fish don't like it that way, its awfully pain to be beheaded. I do saw goldfishes survived after awful sickness, torn tails, breathing difficulties etc. Their torn fins recover very fast, I do have one with both front fins nipped off till left with 1/4, but it regain its fins after few weeks time. Give him or her a chance. BTW
