Thats awesome! Im buying a couple.
I had some people over at my house once and found a dog turd floating in my tank. Everyone played stupid. I told everyone present that if i found one more thing in my tank I would hurt the nearest person until the guilty party confessed. Then I would beat on them. Later that day I put some squash in the tank for my plecostomus. Suddenly everyone wanted to pull me aside and tell me about how someone put vegetables in the tank, but it wasnt them! LOL
