I am looking for an alternative to cork bark in my in amblypygidsenclosures. It is very expensive and I would like to find something that works just as well but is not so expensive. I know I could use untreated rough hard wood (cut-to-size) but it will mold. Has anybody tried heavy Styrofoam cut to size? I have used it temporarily with amblypygids and they were able to hang on it and walk on it. My concern is that it will not provide an adequate attachment for when they molt and they will fall during or after molting and then they will die. Has anybody tried heavy Styrofoam cut to size and also had a successful molt? I do not want to try it and then have one of my amblypygids die of a fall during or after a molt. Thanks for all your help!
