The EcoRock Frag Plug Holder is a functional and natural-looking solution for securing coral frags in your reef tank or aquarium. Measuring 2.25" x 2" x 1", each piece is crafted from real rock material combined with calcium carbonate, giving it an authentic texture and weight that closely resembles natural reef rock. The irregular, rugged exterior blends seamlessly into existing aquascapes, whether resting on the sandbed or nestled within rockwork, maintaining a clean and cohesive reef aesthetic. A precision-drilled center opening is sized to securely hold standard coral frag plugs, keeping frags upright and stable during placement, healing, or grow-out to help prevent tipping or shifting. The uneven contours allow each holder to sit naturally without looking out of place, making it an ideal addition for hobbyists who want both practicality and a polished, natural appearance in their reef setup.
