How to put him down?

[HappyPercy]

If you read my last post I've decided to put Kisses down. This is a very hard decision but I think it is the right one. I have a bucket and I have the clove oil but I can't remember exactly how to do it. Can anyone let me know how to humanely put a fish down?

I think you came to the right decision. Sometimes it's the best we can do.
Found this in my files:
"Clove oil is used to anaesthetize fish and is fatal to fish at
doses greater than ¼ ml per litre of water.
Add 12 drops of Oil of Clove per 1 gallon (3.84 liters) of
dechlorinated water.
Oil of clove is very hard to mix so you may want to emulsify the
clove oil by placing
it in a smaller amount of water in a glass jar and shake well.
Place the fish in a container
large enough for it to move around freely. add the clove oil solution.
Once the fish turns on its side, watch the opercular movements
(respiration/gill movements).
The fish can be removed from the solution after at least ten
minutes have passed since the
last observed opercular movements (respiration/gill movements). "

A zip lock bag with a little water and put in the freezer, they are poikiotherms, it is easy.

If you are a breeder you can also store for reference

A website recommended putting some salt into the bag to lower the freezing temperature of the water. The reason for this was that fish can still be alive by the time the water are forming into ice crystals, which can be a painful way to go.

I've used clove oil in the past. I think it's the most humane way to put down fish since it's basically an overdose of anesthetic. A lethal dose of clove oil until gill movements have stopped for at least three minutes, then into the freezer to be sure.
Best of luck. It's always tough to euthanize.
