I'm currently looking into upgrading from my 75g to something around 240g. The two options that I'm most interested in are either the IM INT 240 or going through Glass Cages for one of their "bundles". The IM tank is about 83"x30"x22" and the Glass Cages tank I'm looking at is 96"x24"x25". I'm somewhat inclined to go with the GC tank, as I think the extra length would fill the wall and allow more space in front of the tank. If I'm planning on doing some large tangs and maybe angels, would the length or width be more beneficial? My current tank is 20" wide and it seems like 24" would be plenty (and easier to reach the back).
