Just looked at your pics in your album. You definately should add some more plants for cover. Especially large leafed plants...pothos is good but there are many others. Take a look at the indoor plant section of you local Walmart, Home Depot, or Lowes. Rinse the plants completely before putting them into your viv including discarding all the original soil the plant came with and rinse the roots. Check out the care article on the left about building a dart frog terrarium. In that article it talks about how to properly set up a drainage layer for the plants to stay healthy. Live plants are a good way to maintain the proper humidity and they also provide for a more natural environment for the frog. Give your frog as many branches and large leaves as you can. This will help him to acclimate better and eventually he'll stop trying to escape.
