If you're going for as much tank as you can fit into a ~30" space, then that's kind of it for standard dimension tanks. Big difference in apparent size vs a 29. The latter seems relatively small compared to it. But overall it's better as a fish tank than a planted tank I think. I have a huge piece of driftwood that pretty much fills mine with plants and moss all over it. Some crypts at the bottom. Real tall crypt spiralis behind as a background.
Personally, I think I'd rather have a smaller nicer long, low rimless tank in the same space. But depends on what you want.
