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:
Some fish are a bit shy when their home is moved and stick in the inside so make sure you do not scare them more than necessary!
About once a month, a slightly more thorough cleaning is recommended. Remove the decorative item carefully from the aquarium and place it in a bucket of aquarium water, as sometimes there are fish in it. Carefully use a safety net to put them back into the aquarium.
