Finally the perfect Holey Rock Module!! This is a huge piece measuring L15" x W9" x H5" . These Holey Rocks can be used free standing, placed against the glass or stacked with other pieces creating a one of kind look. They sink imediately and are perfect for established tanks. With most of these Holey Rock pieces they are delivered with only a few holes cut out, which means you have complete control of how "Holey" your Holey Rocks will be. Anywhere you see an indentation you can cut out another hole with practically any sharp knife. This piece weighs approx 3lbs. Compare that with a real piece at 30lbs.
This piece is made of revolutionary flexible material that is completely aquarium and reptile friendly and will have no impact on the color or quality of water. It is easily cleaned with water and stiff brush. It is very easy to cut and customize as needed using a utility knife. This piece will also sink right out of the box! It can be installed with aquarium silicone or with enclosures with wood backs so you can use screws to secure them.
