I think you're right about snakes not really lending themselves to my particular set up. Sigh. I got in the plants today and they've added so much beauty to the enclosure that I'm now worried that adding a snake may end up in the death of my ferns from uprooting.

Perhaps it's time to admit that frogs or a lizard might be happier in this set up than a snake.

Aren't legless lizards burrowing reptiles? Once the moss takes hold I don't think there will be much to burrow in.
