Sorry, I can not help you out with your critters, however I delved into a vivarium before. I used to have a few poision dart frogs for about three years- When i was moving, my land lord threw out my culture of flies, I live in the phoenix area and it was in the middle of summer so any flies shipped to me cooked.. my frogs starved that summer . the tank i had them in is now a saltwater tank.... sorry about the rambling...
if it means anything to ya, I had tree bark for the background in my tank, you should be able to find them in fairly thick nearly flat slabs at your lps...
very cool idea about how to keep the gnats down
