Decorate your aquarium with a large skull holder for your corals. This skull measures 2.5 inches tall and has a 1-inch-deep bowl perfect for your favorite torches, or any other corals to be displayed. Just like our small skull, our large skull is created with reef-safe, non-toxic mortar. This skull also comes in our reef-safe non-toxic acrylic colors. We offer our Royal purple, the same used to color our Royal Reef Rock and used to emulate the naturally found Coralline algae, and Bone which has been color matched to our Pristine Rock.
