My little Paludarium

Hello!

My paludarium is slowly growing and so far I'm happy with the progress.

I've two concerns at the moment:

1. In the back the philodendron seems to die… probably it's too wet.

2. I use a small waterfall to produce circulation for the water and to help to satisfy the oxygen for my 4 amano shrimps. Together with some snails they are the clean up crew. But the water is noisy and the water sprinkles everywhere .. help?!

Feel free to give me some feedback and assist.
It'd my first paludarium.
