Plastic Bottle Axolotl Tunnel

Turn a plastic bottle into a tunnel for your axolotl! Select a plastic bottle that can easily accommodate your axolotl. Cut a hole in the bottom of the bottle and sand or burn the edges of the hole so that they are smooth. Use aquarium silicone to glue the bottle on top of a rock, and glue pieces of fake plants to the rock and the top of the tunnel for added decor.
