That is an option. Especially Since I can get the 20 inch option and hang it slightly higher. The tank will have an "island" scape that will leave the outside
3-4" Completely barren minus some bare sand. The only two hesitations I have are how I would hang it, (appears to be designed to sit on tank) and are the moonlights on there on individual cord or just a seperate switch. I'd prefer the ability to have seperate cords to run timers.
