    I love my 40B, but am upgrading to a 75 acrylic. Picked up a new tank and stand on the cheap (needs a metric fork ton of sanding, polishing etc, but worth it). As you can see my 40 is getting a bit crowded and I just so happen to have the wall space + found a killer deal. Debating on the new...
