Hate to ask this...

But what’s the best way to euthanize a fish? My molly has had the TB and Ich for a while, I fear she is just suffering for the QT for about 3 weeks now

Clove oil. I have heard vodka works.

Wrap it in a wet paper towel and put it the freezer.
For absolution, wrap it in a news paper and deliver a swift, precise blow to the skull. Instantaneous. A little barbaric for some.

Ice cubes in water allowed to chill a moment drops most fish that fit in a cup in under 10 seconds.

Never fun but sometimes what is best.

Yes never a pleasant part of fish keeping.

For future needs, pure clove oil without alcohol in it anesthetizes them, with the proper dosage will put them to sleep permanently.
