whats the best subtrate ?

[stretch]

I'm housing a pair of pacific tree frogs and was wondering whats the best subtrate. I was thinking those little aquarium pebbles. If anyone has feedback on if this is good or bad please let me know.Thanks

We had some Pacific Greys for a while and they seemed to do best in a live planted tall tank with a dry area,(aquarium pebbles/sand will work) lots of branches, hides and an area of damp not wey spaghnum moss. And a place to take a dip, about 2-4" deep.
