I'm buying a Bumble Bee Walking Toad tomorrow and I have a few questions.

1. I just bought a Exo Terra 12"X12"X12" terrarium. Is big enough for two BB Toads?

2. Is it better to have two toads or is one O.K.?
(in other words: Will one do better alone or does it need a "play buddy")

3. How big of a water dish do I need?

4. What's the best substrate to use?

Thanks in advance!
