Oh I will second the molding bark! I ran low on cypress and mixed in some "reptibark" chips from a friend and would occasionally find nice little blue moldy bark pieces in there. It wasn't a huge pain to scoop out the area but I'd rather not mess with it. The bark was also super dusty. I also found that the bark chunks weren't as "comfy" for my snakes. My bigger girl would get pink spots and indentations on her belly from the big chunks. I like the softer shredded cypress and aspen for this reason.
