How To Euthanize A Fish Humanely

My fish are one by one dying of possibly fish TB. Once they get sick they won't bounce back. All of them are probably going to get it but when they do I hate watching them for days on end in pain. How do I euthanize the sick ones so they go quickly?

 

Clove oil. Also, I hope you’re aware that it’s contagious to you and you shouldn’t put your hands in the tank with any open wounds. Be sure to wash your hands after

 

Sorry you’re having to consider this option, some information here you may find useful

 

I find clove oil is the best most peaceful way. Whats this sickness that is taking over?

I believe its fish TB. I'm treating for a few things just in case, but if it is TB they don't have much of a chance.
