Designed for versatility, subtlety, and smarter coral placement in your reef tank.
 
These Black Frag Plugs are an ideal choice for reefers seeking a cleaner, less distracting look. Their dark colour blends seamlessly with most aquascapes, unlike traditional bright white alternatives.
Each plug features a subtly textured top surface with a small central divot, helping glue or putty hold more effectively and making them perfect for SPS frags. No more trimming stems either – the plug stem is fully detachable, giving you flexibility without the bone cutters.
Available in two shapes – a 25mm round top or a 27mm square top – both styles are 20mm tall with the stem attached. They’re also fully compatible with our FragDoc system, which is 18.5mm tall and 15.5mm across, allowing you to securely dock and remove your frags with ease.
Note: Unlike some 3D-printed alternatives, these plugs are designed with sufficient density to ensure they sink reliably, enhancing their functionality in your reef setup.
 
Note: The FragDoc docking base is sold separately and shown in some images for demonstration. You can find it here.
