CaribSea South Seas Arches and Caves Dry Live Rock Aquarium Décor - 20 Lbs

CaribSea South Seas Base Rock – Arches & Caves (20 lb) – Natural reef-style limestone rock pieces shaped into archways and hollow caves, perfect as foundation rock for marine or freshwater aquariums. These porous, fossilized coral rocks mimic the structure of a reef, providing plenty of surface area for beneficial bacteria and hiding places for fish. Use them to create stunning swim-through caves and arching rock bridges in your tank. South Seas base rock is free of organic matter and pests, making it a safe, eco-friendly choice that will eventually become live rock in saltwater tanks or add beautiful calcium carbonate scenery to African cichlid tanks.
