Ceramic Nature's Stacking Plates allow for the easy placing of Ceramic Nature's Caves into a realistic and convenient pile. These can either be left as they are (in a breeding tank) or scaped into a display aquarium. Made from high-quality clay, Ceramic Nature Stacking Plates are colourfast, extremely durable, and easy to clean. This large stack plate has 4 waves, which means there can be 4 breeding caves underneath and 3 on top. (Caves not included).
