Probably going to buy a 40 breeder soon for my first aquarium in over a decade. I have a cat now, and he's a pain. He will jump on top of the tank until he has decides it's no longer fun and there's not much I can do about it. I intend to use a glass versa-top lid so I can add an LED light bar, but they seem pretty thin and I'm worried that he could break it. Plus the 40 gallon breeder top is about as big as versa-tops get, thus increasing the stresses on the glass. He's a normal-sized cat, about 11 lbs. Anyone have experience with this? Should I go with the versa-top or should I possibly DIY the lid with thicker glass? Thanks in advance.
