Dirt or moss or ?

I would certainly appreciate it if you could do something like that (write a tutorial). The biggest problem for me was finding the right material to form the water basin. I settled on a large glass Pyrex bowl. It made things simple but also meant the water feature is contained rather than tank-wide.

As for the pond...just make sure you have deep gravel (4"), and keep the water table below that...maybe 2"...you'll get a feel for what's what. Then just dig out a depression pond in the gravel, take some river stones and push them into the sides to help it hold form...simple...natural pond. This allows all the water in the "resevoir" you've made to flow throughout the bottom of the tank, oxygenating the water and creating a 4" deep undergravel filter.

NOTE: This method has been used very successfully for small frogs. A six inch toad in a 20 long is not going to work like this. Your ratio of poop to plants to water has to have a balance.
