South Seas Base Rock - Natural feathering processes form the fantastic shapes of South Seas Base Rock by the erosion and pitting of limestone over the course of eons. It is clean and safe for marine, reef and hard water freshwater aquariums such as African cichlids. South Seas Base Rock can also be an interesting and realistic addition to a desert reptile biome.
I would definitely recommend adding these little guys to your tank. They are very playful and entertaining. My three were very healthy and quickly adjusted to my tank.
