Ugh. I just remembered an incident from about 5 years ago.....One of my fish died, and as I was scooping it up out of the tank to flush it down the toilet, I was baffled because I couldn't find one of my other fish.

Then, as I was saying goodbye to the fish that I scooped up, I saw that I had accidentally scooped up a live fish with the dead one...and there it went, down the toilet....What an awful, awful experience.
