These light natural-looking Handmade fired ceramic rocks, with cavities, fissures and many other smaller openings provide shelter for a varied micro-fauna. The porosity enables a great deal of bacteria and micro-organisms to flourish and the whole arrangement becomes a filtration medium. Irregular shapes enable you to easily build grottoes, arches and all sorts of arrangements in order to create an environment where fish feel at home. In a fresh water system, as well as in marine, these rocks contribute positively in the ecosystem of the aquarium. In a few months, a matchless patina will give a very natural effect. Used singly or together with our other ranges, they offer a great number of possibilities to decorate different aquariums.
