I discover a neglected fish tank that I forgot about. I think it is by my bedside, but maybe I move it there so that I won't forget about it again. There is a plecostomus in there that is large like the one I had that died a couple months ago, but he looks quite sickly. I realize that it wasn't my pleco that died, this is my pleco, and the one that died was a different one I got from somewhere.

I need to filter the water, which is filthy, but the tank is down to about a quarter full. There isn't enough to filter. I decide I'd better just get add some fresh water as quickly as possible.

All the other fish seem to be just fine.
