I have a 30x12(w)x18(h) tank -- 30 gal, I think -- that I was considering laying down sideways, and using some screen doors for the front (which used to be the top). Since bp's really aren't climbers it doesn't need the extra height, and it would have a 30x18 floor space. However it would be closed up all on all sides except the front. Any thoughts on this?
