This lifelike decoration is made of polyester resin. It is completely non-toxic and does not affect the biological balance in your aquarium.

The natural-looking hole rocks provide optimal handling for plants and microorganisms. Hiding and shelter possibilities are limitless.

The decoration is suitable for both freshwater and saltwater aquariums. In combination with the other sizes, a rocky landscape can be simulated.
