HCA: Hermit Crab Association

I have decided that a 100watt ceramic heat bulb would probably be best for my 39-gallon tank. I have read that you cannot put them directly into the tank(for obvious burning-related reasons). I have a flourescent light strip and a black(plastic?) lid. How would I go about setting up a ceramic heat lamp so that I wouldn't lose humidity?JJHermit

You will need one of the metal reflecting light fixtures they sell in the reptile section of pet stores.Then you'll need to affix this fixture (usually it's clamp-style) somewhere above the crab tank aimed down into it. Adjust the distance to get the proper heat, and adjust substrate moisture and lid propping to retain humidity. I wouldn't put 100w emitter closer than 2 inches from the lid or plastic might melt.
