I've been reading alot about DIY aquarium canopy and I think it looks really nice and I am planning on making my own later but I have a few questions like how are you suppose to protect the fish or the lighting if you keep fishes that jump like arowanas,and what about filtration. A lot of pictures of canopys that I seen doesnt have any room for filters like the HOB's. How am I suppose to make room for my filter without having a canopy with a big hole on it?
