Agree with what you saying. I hate when animal experience fear either. When me and my coworker euthanized that betta we followed this
It was long time ago but i remember i didn't like it a lot because i think he was still alive when we put the liquid with clove oil in and i didn't like his reaction. So yes i kind of afraid to do it. The doctor that i am working for told me if i will ever need to do it again he will help me.
And its so nice that we even thinking about the best way to do it, you know how many people just flushing poor fishy down the toilet.
Ok thank you for the update and i will wait for another one :)
