Frag rocks are rock cut flat on the bottom or left natural, and drilled to fit frag plugs. Frag rocks are great for growing out corals with the ability to move the coral covered frag rock as the coral grows onto the rock. They come in a variety of shapes and sizes which makes them versatile in any aquarium.
Current selections include:
SINGLE; DOUBLE; TRIPLE
Single is drilled with one hole to fit one frag plug, double is two, and triple, three.
