I looked into the Fluval FX6, and it looks way too big for the my setup. I'm currently looking at for the water enclosure, 32 inches in length, and 8 inches in height, leaving 16 1/2 inches (length) for land. I think 8 inches should be enough (height wise)-agree, disagree? What about the Fluval 406 External Filter? I'm really liking the Fluval 406 external filter in the 45 gallon. I appreciate your help- thanks so much! Ah, yes, the hygrotherm controller- I was actually looking at Zoo Med for that
