Disappearing Goldfish
My goldfish keeps disappearing from the tank! This is the third one now. It's not dead like there's no "scoop dead fish" it's just gone! Is the piranha eating it or something?

I had this happen when I mistakenly put goldfish and black goldfish in the same tank. All the goldfish started disappearing. It took me a while to figure out they were being eaten by the black goldfish.
