Features & AdvantagesEasy care polyresinPorous structure offers hiding placesNatural & lightweightHarmless for water, animals & plants
Lightweight with a natural look - thanks to their authentic appearance, the Cavity Stones allow a natural design, e.g. superstructures or groupings, and are no danger to aquarium floors or walls due to their low weight. The porous structure offers animals numerous hiding places; mosses or perching plants make the stones into lively decorations.
The material is easy-care polyresin, it neither affects the water quality nor clouds the clarity. Thanks to food colouring, the decoration is not harmful to animals or plants - it can be used in freshwater aquariums and terrariums without hesitation.
