DIY Monster Head Cave

Make a cave for your aquarium that looks like a monster head! Cut off the top rim of a plastic container and cut out holes for eyes from the bottom section of the container. Place the container bottom at an angle inside the plastic rim to create the mouth and use aquarium silicon to glue the plastic in place. Break slate tiles into small pieces and glue the slate onto the container. Cut plastic plants into small pieces, glue the plants onto the slate, allow the silicone to dry and soak the cave to remove any chemicals before placing the cave in your aquarium.
