LOL yeah I figured that would be suspected, but this 90 gallon tall is pretty out of his reach on the top of a double iron stand, and the lid is pretty hard to open the way the lights sit across it. He likes to look at my baby fish, but he doesn't really have much interest in getting in the tanks either. I'm pretty much the only one that gets in the tanks, aside from the occassional water changes my daughter helps with. No big fish pranksters in my family, or that'd be my first guess!
Still trying to find another guppy that has a tail slightly resembling the tail on this one.
