One of my neighborsneighbor's fish coincidentally died during the time I was caring for them. I immediately removed it from the fish tank, but I didn't know what to do with it. Flushing a pet down the toilet seems rude, and it might block the pipes. My mom suggested to leave it in an open space so any bird or street cat can eat it.
When I think about it now, I fear this fish might have carried a disease which could spread to its consumer.
What is a respectful way to dispose of a dead fish's body without affecting any other life form?
