ASHBA specializes in aquarium inserts as seen on Animal Planet's hit TV Show TANKED. We build custom aquarium coral & coral inserts. All of our coral is carefully molded from actual coral skeletons and casted using a specialized, urethane rubber which is aquarium safe. Our coral is very durable, stretches and is wear resistant. Don't be fooled by other imitation coral, our corals are not painted but are infused throughout with color so our products will not deteriorate and can be brushed or soaked as needed.
