in reality, no matter how expensive, its still kinda maddening! my male dog, actually likes to hang around, on tank cleaning to, he catches the jumper. He saved a bala that way, he caught it, I hadn't realized that it jumped, and I saw him playing with it. It lived for a few more years after that! then jumped , and the dog wasn't around . He also killed a frog that way to though, lol, he was a little rougher with it!The pleco discs were only $5, but I did bring them back from England with me...
