Hello all. My name is Will. I used to frequent the caudate.org forum a lot and I joined this forum in its beginning with the hopes of acquiring some type of frog, although that ultimately did not come through. After a four hiatus from keeping pets and participating in various forums, I have decided to take one of my old tanks and construct a dart frog vivarium (an area I never ventured into in my past). I have been researching this forum and other websites for ideas and information the last couple weeks. I went to Home Depot today to buy supplies, but I could not find Great Stuff. Instead, I bought DAP Polyurethane Fireblock Foam Sealant. I was wondering if this was safe/effective to use as a background? I bought it thinking I could always return it if not.
