Awesome! Whenever I see something like this, I wish I had more space to set up a larger paludarium. Looks like your own little tropical lagoon.
Is that hygro polysperma in the water near the waterfall? Let me know if you have any luck getting it to grow emersed. I've had some luck, but the stuff has difficulty staying upright. Maybe you'll have more luck than me if it grows in a nice thick bunch like that.
Also, where did you get the moss? Did you get it from blackjungle?
