So currently I have no top on my tank, and none of my current 3 fish have shown any sign of jumping or anything and they all seem very happy. In the future I was looking into getting some or a fish that may jump, like the purple firefish.-- any ideas on what to do for my hood, the last one I had doesn't really fit anymore with my lights on it. I have heard glass will block out alot of the light but acrilic will block out alot less. Would it be a good idea to get acrilic and cut it so it would fit my tank? If so where could I get some, do they sell it at normal stores like lowes and stuff? Any other ideas? Thanks a ton!!!
