Advertisement Hey guys! First post, so forgive any mistakes please. I also searched the forums and nothing relevant showed up, so I can at least say I tried to search haha. Anyways, I converted a Pioneer Plastics acrylic clear display case (from Hobby Lobby) into a terrarium for my avic avic, and that went fine. Set up the substrate and climbing materials for her. That was like 2 days ago, and I have yet to move her into it yet. Today, I noticed there was mold on some of the branches I had used, specifically the parts below the substrate. Obviously, the mold grew because it was wet, but because it wasn't really THAT wet (substrate is cool, slightly damp to the touch), and it has only been a day or two since I put the branches in, I'm assuming that the wood I used is prone to mold. My question is what types of woods are good to use in an arboreal enclosure? I bought the wood from Petco so I assumed it was sanitized, but is it possible that the mold grew not because of the TYPE of wood, but because it wasn't sanitized? Would the same thing have happened if it was cork bark and it wasn't sanitized? I don't know what types of wood I can use other than cork bark, but cork bark to my knowledge only comes in slabs, but I want something that I can use as branches. Thanks in advance!
