Thank you, pica (I think

Clove oil is not "poisoning" by any stretch of the immagination. It contains an element that anesthetizes the fish, meaning that it "falls to sleep" almost instantly (the higher the dose the faster), sortof like using ket/val on dogs and cats going in to surgery. However, just like any anesthetic, if you overdose, the animal will die. The reason I suggested freezing afterwords is that, if you put too little of a dose, there is a chance of the animal recovering. By freezing it while it is still anesthetized (and hopefully dead!), you offset the chance of it ever waking up again, and freeze when it is insensitive to pain rather than when it is still responsive. I did this with my own goldfish, and he barely swam an inch before his gill movement halted entirely and he was completely unresponsive to his surroundings; no signs of life. In less than an hour, his eyes were glazed and his slime coat had shed, so he could definately be considered officially deceased. It was an extremely fast "knock out," and probably an almost instant death; and even if it did take the hour to pass on, the animal was not feeling anything.
Cutting off the head is only humane if you also destroy the brain; being cold blooded animals, fish and reptiles can survive long enough with thier head cut off to be in agonizing pain, as it takes them longer to suffocate than warm-blooded animals. There have been numerous accounts of snakes in particular living for hours after being decapitated. So, if you would rather cut off the head (though I think my suggestion is perfectly humane...), you need to insert something into the skull and "scramble" the brains immediately, to ensure that the animal doesn't live for a while after being decapitated.
