Please give me any feedback and recommendations!

This is a 24x18x18 with cork background/sides and two cork tubes siliconed to the back wall. I filled it this week so it needs to grow out. I plan on housing either Ranitomeya sirensis or Phyllobates vittatus in this.

The drainage layer is mostly lecca, with a thin vertical layer of river stone around the visible outsides against the glass. I used water-repellent folders to temporarily hold back the lecca.

Planned edits: I might move the bird's nest fern to the tubes somewhere for epiphytic growth. I will also add some leaf litter soon and hopefully another hide or two before I get any frogs.

Specific question: Should I keep the elevated cork tubes open for the frogs? Or should I plug the center gap to make two hides, or just plug the ends so the frogs can't get into them at all?

I failed at my first open-top paludarium and let these driftwoods with moss wrapped sit in there while it dried out. Can I just boil them for 20 minutes each and be good to go? Or should I also do a hydrogen peroxide spray/soak or bake? I'm not sure if the black parts are from sitting in the Fluval aquarium substrate or rot - would this matter? I see what I assume is white mold on the walls but it could also be the white aquarium sand residue
