I need to euthanize a fish. I heard that some anesthesia called MS222 is the best for this but I can't find it anywhere, and it would probably be expensive anyway. The other option is clove oil. Has anyone ever done this and if so, is it effective? In case you want to know, it's an old fish with a congenital disease (probably from inbreeding) that doesn't want to eat anymore. I can either destroy it or watch it slowly starve to death, which is depressing and maybe inhumane.
