We used to have 6 fish: 5 various types of mollies and 1 fancy tailed guppy.
One day, when I was looking across the room I noticed the water was getting green. I also noticed the guppy seemed to be missing.
I walked closer to the tank and couldn’t the little blue guy anywhere. 2 weeks later when the water was more like pea soup I cleaned the tank. There wasn’t even any evidence of his bones. Did he disintegrate or did he get eaten? Did he become weak and get sucked into the filter? I know the cats didn’t do it because there’s a glass top on the tank all of the time.
You’re my boy, blue!
