Red eyed Tree Frog Housing?

Question

I dont have a red eyed yet but when i do get one or two i want to put down some smooth pebbles on the bottom and fill the bottom with an inch of water and have a little waterfall thing instead of eco earth or stuff like that, i thought it would help keep humidity up and i read that they are good swimmers, would that be ok to do that or would it be best just to have a water bowl and some eco earth or something, also i thought it would drive the crickets up higher where the frog would normally be

This species tends to do better in a community.  

Answer 2

ok the crickets will down themselves (i dunno why they just do) remember red eyes are very fragile any problems with there habitat could lead to serious issues so i would stick to whats advised
