Now that I think about it the most intimidating things about the viv tutorials I've seen are the water features. Filter arrangements look troublesome. I'm thinking about putting down a drainage layer, put in some plants (pothos, snakeplant, lucky bamboo), add some springtails and just use a very large water bowl for frog soaking purposes. Oh. and I finally gave in and bought the terrarium. Yep. Thanks to this forum I'm also preparing a tall plastic storage bin as a travelling frog-carrier or emergency tank. That was a really useful thread.
