I live in Fl and due to the hurricanes earlier this year, we have an abundance of downed trees. Most have been sectioned up for removal and I recently noticed several pieces near by where the bark is seperating from the wood. The pieces are coming off in very clean sections, some of them nearly tubes. They are very similar in form to the cork bark sections sold in pet shops but seem much stiffer. I'm wanting to set up a 60g oceanic cube tank I have (24"x24"x24") as a vivarium and was wondering if this bark would hold up. I thought I might fill the insid with Great stuff to preserve the tree shape and use it as a background. Any thoughts on the subject would be greatly appreciated.
