Thanks for all the replies. The fish is still alive and sitting there on his rock, eating a flake from time to time, but not much. I don't think my wife really wants to deal with the subject so if the fish appears to be laboring rather than just sitting there, then I'll euthanize at that point. It's such a small fish I don't think it matters how it is done. I could probably just pinch it between two fingers and would hardly feel it.
