I've considered that, but the way I have the tank laid out, it's sort of a divider between my sitting area and my poker table. Since its sticking out of the wall length wise not width wise, I may add a black background to the side against the wall though, not a bad idea.
Danky: Let me know how the temperature adjustment works out for you. During the summer I will probably not run the heater at all and may get a fan to attach to the small acess lid.
