I am wanting to get a second tank and have a corner in mind. Ive been looking and see the usual rectangle shape tanks, but is there any problems with asking the manufacture to make me a square base and tall tank? say 55cm square bottom and 60 to 70 cm high? (sorry don't know what it would be in inches). I'd like to put plants, a couple of severums and some type of bottom feeder. What does anyone think? Thanks heaps....
