Re: Aquarium tear-down for PDF Paludarium
I want to know the answers to your first 2 questions as well!
I've seen people use Hygrolon on their walls to help spread moisture, in place of a drip wall.
For the 3rd question, isopods typically utilize about 2-3 inches (5-8cm) of substrate depth, depending on the species.
I can't help with the dart frogs though. I've read they're not the strongest swimmers, and they can't understand that glass is a wall they cannot pass through. So there's a risk of drowning. Someone correct me if I'm wrong, please.
For question 5, I'd assume it would keep the enclosure warmer, but it might also increase humidity to undesirable levels. You'd really need some fans in there probably.
This is just an assumption though, hopefully someone with more experience can chime in.
