Years ago, I think it was called Nature Tech, or First nature or something like that (it was either a sub company of Tetra, or what later became tetra) had a really neat setup that used half the tank for land with a pump and water fall. I can't even find the things on ebay as they've been discontinued for years, but I always thought they were neat. And I still see them a lot in the LFS's that have been around for a while for newt and crab tanks.
