HCA: Hermit Crab Association

When I first got my crabs I bought a half log and a wooden tunnel. They hide inside them and crawl all over them. I have heard some types of wood are not good for crabs so now I don't know how safe they are to be using. I am not sure what kind of wood it is but thought I would go back to the pet store and look for the pieces I have with labels still on them. Hopefully the labels will tell me what type of wood it is. Can anyone tell me what should be avoided? Thanks, crab happy

A great place to get wood online, that I've used many times, is:http://www.blackjungle.com/home.htmI've got cypress in my tank, and I haven't done anything with it since February, and it still hasn't shown any sign of mold. I might try the ghost wood too, as it holds up really well to humidity without molding.
