Thanks to everyone for looking and commenting; you're too kind. We bought this form factor because it was on sale at the time, and we needed something with minimal impact on floor space (this one was advertised as a corner tank, but we have it out in the middle of the living / dining room now to help divide the space).
I really don't know what I'm doing, scaping-wise. One thing I did was take some clear suction cups and air tubing, then cut small sections of the tubing, and slice down one side, to make anchors for the plants on the side of the tank. I am sure there's some better way to do it.
I believe the tank is the same one shown at the following link, making the dimensions 20 3/16" W x 18 3/16" L x 63-5/16" H:

My next wishes for this tank are to hide the equipment a little better, to replace the fake rock in the middle with a tall piece of mangrove root
driftwood, and to redo the bubblers to look like marsh gas, something I did in our other tank.
