As far as substrates are concerned, I wouldn't use pebbles (or Bam-Bam ). I would set up a false bottom (see the red-eyed leaf frog article for instructions), with a layer of LECA or Hydroballs, a layer sphagnum, then a layer of leaf litter (live oak leaves work well for this, available from Josh's Frogs). Or you can put a layer of LECA directly in with a fine mesh above it, the a layer of coconut bedding (possibly with some sphagnum mixed in), then the layer of leaf litter.
