St. Kitts Plug N’ Play Rock Base is your way of bringing a bit of the sea home. This base has pre-set holes for our artificial corals, which can be purchased individually. The natural rock color of this reef rock can be found on your nearest coast. You have the option of picking between four different encrusting sponge colors or no sponge color at all. This piece was designed to have an arch to give your fish a place to swim through.
