I am thinking abut getting a 45 gallon Octagon type tank in replacement of my 55 gallon tank to conserve some room when I move to Las Vegas. My girl friend and her daughter are moving in and I am in need of more space. I like these since they can go in a corner or along a wall. But first I would like to here from some folks who own or owned this type of tank or maybe a friend has one, and get there thoughts on them, good and bad. Thanks.
