The wife want me to have some storage space for all my fish related crap & if I go 12' I don't have the room for the towers I want to build. There are a couple lights & a thermostat on the wall that I don't want to have to relocate if I can help it, there is also a closet on the left end of the tank where the door swings out 2' where we keep all our movies & holiday decor which I really can't block or the wife would put an end to the whole new tank.
