Christina!!! First, way cool tank you linked to.

Second, I love the idea of the stream tank with a view of the stream, and alligators?????!!!!!! WOW!!!!!!!. I want a huge planted tank with a number of 3-4 foot Florida Spotted gars hanging out. They're the fish version of the alligator and if given a big enough tank they should get close to the size they get in the wild, 3-4 feet!

I so like the idea of being able to veiw a stream with a long window. You'd have to have some pretty massive pumps for that, but hey, we'll all be rich soon right?
