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

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

Our expert Oliver Knott recommends:
Even if your fish are shy at first, they will soon inspect their shelter, be patient!
When returning your cleaned decoration back to the aquarium, first siphon off the soil it was standing on to remove any sediment or other waste created in a busy aquarium.
