Thanks so much both of you, those sites look great. But how do I know what is safe for which frog, or are they all pretty safe? I'm new at the live habitat thing. I currently have 1 chubby frog (I know I have to use pots with him cause he'll dig the plants up if not), 1 dumpy tree frog, 1 cane toad (although he's not doing so good ), and I may be adding a tomato frog.

Also can someone answer a couple more question?
So by creating a living habitat its like creating its own eco systems right? What kind of clean up do I need to do? Do I change out the substrate completely and if so how often? Does anyone have any tips, sites, anything that will talk me through this more?

Thanks again
