Description
Product Overview
Reefing Art’s Ceramic Coral Frag Plugs are meticulously kiln‑fired to create a dense, non‑porous ceramic that will not generate grit or dust in your aquarium. Each plug measures 7/8″ in crown diameter with a 3/8″ base, providing a stable platform that mimics natural reef rock. Weighing 8.5 grams (approximately 1/4 oz) per plug, the heavy weight ensures that even the most delicate SPS or LPS fragments stay firmly in place, even in tanks with moderate water flow. The new surface design incorporates a rough texture and a central hole, both engineered to improve coral attachment and promote faster tissue growth. The package includes 100 plugs, enough to outfit a medium‑sized reef system or to keep a stock of spares for future frag placements. Additionally, a free bottle of RA aquarium coral glue is supplied, giving hobbyists an extra bonding option for especially fragile or slow‑growing fragments.
Dimensions are compact at 0.88 x 0.88 x 0.04 inches, allowing the plugs to fit into tight crevices and tight spaces where natural rock would be difficult to position. The plugs are chemically inert, ensuring they will not leach any harmful substances into the water, and they are compatible with both SPS (Small Polyp Stony) and LPS (Large Polyp Stony) corals, as well as zoanthids and other soft coral varieties. The product has earned a solid reputation among reef enthusiasts, reflected in a 4.3‑star rating from over 190 verified purchasers and a Best Sellers Rank of #29 in Aquarium Décor Coral on Amazon.
Beyond the functional aspects, the aesthetic of the plugs adds a subtle, natural look to any reef setup. The ceramic’s muted, off‑white hue blends seamlessly with live rock, creating a cohesive visual environment that enhances the overall appearance of the aquarium. The plugs are also easy to clean with a gentle brush if any algae or detritus begins to accumulate, and they can be reused after coral removal, making them a cost‑effective and sustainable choice for long‑term reef keeping.

Usage
These plugs are ideal for both beginner and experienced reef keepers who need a reliable base for coral fragments. Place the plug on a stable rock surface, apply a small amount of the included RA glue to the central hole, and gently press the coral fragment onto the plug. The rough surface texture encourages the coral’s tissue to grip the plug, while the weight prevents the fragment from being displaced by water movement. This method works equally well in high‑tech SPS tanks with strong lighting and moderate flow, as well as in more relaxed LPS setups where gentle water movement is preferred.
In addition to primary placement, the plugs can be used for propagation projects, such as creating a dedicated frag station or a “frag wall” where multiple plugs are arranged in a grid pattern. This allows hobbyists to maximize space efficiency while maintaining optimal water flow around each fragment. The plugs also serve as a convenient tool for repairing damaged corals; the included glue can be used to re‑attach a fragment that has broken off, giving the coral a second chance at growth. Because the plugs are non‑porous, they do not harbor bacteria or parasites, making them a hygienic option for quarantine or disease‑free propagation.
Why Choose Us
Reefing Art has a long history of producing high‑quality reef accessories, and these ceramic plugs are a testament to that commitment. Each plug undergoes a rigorous quality control process that includes dimensional checks, weight verification, and surface inspection to ensure consistency across the entire batch. The kiln‑firing process eliminates any residual moisture, guaranteeing that the plugs will not swell or degrade over time, even in the demanding environment of a marine aquarium.
Customer support is a cornerstone of the Reefing Art brand. Should you encounter any issues with the plugs or need advice on optimal placement techniques, the company offers responsive email and phone support, as well as a comprehensive online knowledge base. The inclusion of a free bottle of RA aquarium coral glue further demonstrates the brand’s dedication to providing a complete solution for coral fragging, reducing the need for hobbyists to purchase additional adhesives separately.

FAQ
Can I use these plugs in a freshwater aquarium?
While the plugs are chemically inert and safe for marine environments, they are not specifically designed for freshwater tanks. The rough texture and weight are optimized for coral attachment, which is not a typical requirement in freshwater setups. For best results, we recommend using them only in saltwater reef aquariums.
How many plugs should I use per coral fragment?
One plug is generally sufficient for most SPS and LPS fragments. Larger or more delicate fragments may benefit from using two plugs placed side‑by‑side to distribute weight evenly. The central hole allows you to apply glue to both the plug and the coral, ensuring a secure bond.
Are the plugs reusable after coral removal?
Yes, the ceramic material is durable and can be cleaned with a soft brush and aquarium‑safe water. After removing any residual tissue or glue, the plug can be sterilized with a mild bleach solution (diluted 1:10) and rinsed thoroughly before reuse.
What is the advantage of the rough surface compared to smooth plugs?
The rough surface mimics natural reef rock, providing micro‑grooves that coral tissue can latch onto. This increases the surface area for attachment, reduces the time needed for the coral to secure itself, and improves overall survivability, especially in high‑flow environments.
Do I need to use the included RA glue, or can I use another adhesive?
The RA aquarium coral glue is formulated to work specifically with the ceramic material, offering optimal bonding strength. However, you may use other reef‑safe adhesives if you prefer, as long as they are compatible with marine environments and do not contain harmful chemicals.
