Safe material: Made from natural, fine compressed sand with a very flat and smooth surface and edges, it is absolutely safe for your fish and it also filters and purifies the water. It is suitable for small bream and cichlids when they need to rest or breed. A feast for the eyes. This hidden cavern offers a visual feast and a “house” for your fish. The cavern allows fish to stay and visit, or as a resting or hiding place to reduce stress and minimise cichlid aggression, and is the perfect place for bettas, crayfish or crustaceans. Easy to stack: the cavern has a flat top that can be stacked and you can angle the hole in any direction. Please note. Please check the dimensions indicated in the photos and descriptions carefully before purchasing. The real product is smaller than you might think.
