1" Square Frag Plug

Perfect for securely mounting your coral frags, our ceramic frag plugs are made from reef-safe, high-fired ceramic that won’t leach harmful substances into your tank. The textured surface promotes quick coral attachment and natural growth, while the sturdy stem fits snugly into standard egg crate or rock crevices. Ideal for both SPS and LPS corals, these plugs blend seamlessly into your reef environment for a clean, natural look.
