Who Gives A Fish Forums

I'm considering trying Aqua-Sed from Amazon - it's a fish anaesthetic, and I thought it might make it easier to put my fish down humanely. I've got another diamond head tetra with swim bladder disease and I'm not looking forward to it, to be honest. Has anyone else used this product, or something similar?

Clove oil's the euthanasia method of choice for many on this forum, I've found it works well when I've had to put fish down in the past.
