Another lesson I learned in this hobby is that it's a dart frog's world, and tree frogs just happen to be living in it A lot of the plants you find at Joshs and other places are offered with dart frog vivariums in mind. There are a few things that are good for tree frogs, but most of the tropicals and bromeliads and such are ideally suited for darts, which tend to be smaller and less destructive. These smaller plants can still serve a decorative - if not becessarily functional - purpose in a tree frog vivarium, which is why I suggested you have at least one plant that is fairly robust and broadleafed. Pothos or some kind of philodendron will do nicely. Sansevieria and peace lily are also great choices - although your tank may not be tall enough for those. Fortunately, red eyes are neither particularly big nor heavy of foot, so they won't cause too much damage even to fragile plants. You can add some ghostwood or manzanita branches for more climbing surfaces, if needed.
