Ok so I got a new terrarium for christmas which I plan to turn into a dart frog vivarium. Currently I have the substrate in but I can't help but feel that im missing something. The substrate I added was T-Rex Jungle Bed Premium Blend Forest substrate. Please tell me if I should have added something first. I also have several pieces of live moss, a piece of driftwood, and a single terrarium plant. I will be getting more plants Saturday.
