hehehe... that is our cat, Fluff. She looks really mean in the pic, but she is one of the sweetest, and most brainless cats I've ever owned. She never even looks at my fish let alone bat the glass!!
the first fishy, bubbles, jumped his divider. He had already bitten some of his tail, but.... he got his butt kicked. The other guy, Toro in the 2nd pic was the one who kicked his butt. And he barely has a tear! A small tear in his tail, and part of his ventral fin gone. But obviously he defended his territory well! Bubbles has not attempted to scale the divider again!
