So I have a question for you all. It's been suggested that the Atelopus spumarius need a pond with fresh water running. My idea was to build one by siliconing glass walls at the bottom and back glass of the vivarium. In it, I would use a water filter (clean water is apparently a must) protected by eggcrates to change the sponge easily. I want to add some hydro balls at the bottom for even more filtering, and add natural rocks that we have and pieces of wood. The filter would be used of course to stream the water from the bottom, and push it out from the top, creating a soft stream.

What do you think? Any other ideas?
