great looking set=up!! Mine is a little more boring, no waterfall. I have a 20G long that I just built up one side with river rock, a pagoda rock on each side, and live plants throughout the middle. Someday when my camera is working I truly will post a pic, right now I have too much on my plate to deal with the camera (selling house, going back to grad school, moving across the country. . .).
Just for your information, the first time I put white clouds in with my CFN's two mysteriously disappeared . . . The second time it was fine but I thought the white clouds were a little cramped (10G with 4G or so of water) so I moved them. On the other hand, I had a hitchhiker molly fry in the tank for weeks and they ignored it. So you never know. I would like to eventually redo the tank with more water and try white clouds again and maybe shrimp or clams. I also keep a FBT in there which is not recommended but I have had zero problems, my toad is extremely meek and lazy! There are also a few snails and they are ignored as well.
Just a heads up for you to watch the interaction between the two species. Sounds great and I wish I was setting up another tank!
