I have this centerpiece for my old cichlid tank. It looked like old driftwood that was hollow for the fish to hide in or swim in and out it. It came to me that it might make a good climbing piece for baby dragons to bask on. Since its got hollows in it that could make them get caught or hurt. SO... think I could fill it in with that spray foam in a can that we use for decorations and then seal those spots and use it for a basking platform? It has lots of texture and I thought about scratching it up a little more or adding something to it to make it easier for them to climb on.
