The Barbados Plug N’ Play Rock Base is a great way to bring a piece of the ocean right into your home. This rock base has pre-drilled holes that accept our artificial corals, which can be bought separately. The signature rock color of this reef rock can be found on the nearest coast. You have the option of picking between four different sponge colors or no sponge color at all. This piece was designed to have multiple arches for your fish to swim through and hide.
