If you choose to decorate your aquarium with real stones and massive rocks, you are probably aware of all the risks you are taking. Besides potentially ruining the natural look of your aquarium, cichlids can cause serious damage by digging holes in the sand. Rocks crashing and falling directly to the glass can cause the bottom of the aquarium to break. For that reason, before adding sand, we suggest putting Aquadecor protective rubber mats. Instead of revealing the glass, cichlids digging a hole will come across the rubber mat, which will serve as a protective layer and prevent any damage to the glass. Mats come in more than 20 realistic designs. Your mat can match the color of your aquarium background, or the shade of the rocks you plan to place on it. It is recommended, although not necessary, to cover the entire bottom of the aquarium. A mat can also be placed on those areas where you plan to put real rocks. Available in all measurements, in regular and irregular shapes.
