Acropora Coral: The Crown Jewel of the Reef
Elevate your saltwater aquarium with the breathtaking beauty of Acropora Coral. As the most diverse and sought-after genus of Small Polyp Stony (SPS) corals, Acropora is widely considered the crown jewel of the reef-keeping hobby. This stunning coral features intricate branching structures, delicate polyps, and a spectacular array of colors ranging from electric greens and vibrant blues to deep purples, pinks, and glowing oranges. Under actinic lighting, the colors become intensely fluorescent, creating a dazzling display that transforms your aquascape into a living masterpiece. With its elegant growth forms and dynamic presence, Acropora is the ultimate centerpiece for any dedicated reef enthusiast.
Aquacultured for Superior Hardiness
This frag is 100% aquacultured, meaning it has been propagated and raised in a controlled captive environment. This process yields corals that are significantly hardier, more disease-resistant, and better adapted to the conditions of home reef aquariums than wild-collected specimens. You will receive a healthy, established frag with multiple branches, securely attached to a frag plug. Each frag typically measures 1 to 2 inches in height and is ready for introduction to your system.
For Experienced Reefers
Acropora is best suited for intermediate to advanced aquarists who have experience maintaining stable SPS-dedicated systems. Unlike hardier soft corals or LPS, Acropora requires precise, stable water parameters, intense lighting, and strong, intermittent flow to thrive. However, for those willing to meet its needs, this coral offers unmatched beauty, rapid growth, and a rewarding challenge that is the hallmark of serious reef-keeping.
Lighting & Flow
-
Lighting: Requires moderate to high lighting intensity (T5, LED, or metal halide). For optimal growth and color development, an ideal PAR range of 250–450 is recommended. Higher light levels will enhance color intensity and promote compact, dense growth. Gradual acclimation to your lighting is essential to prevent bleaching or stress.
-
Water Flow: Prefers strong, intermittent, and turbulent water flow. Acropora relies on high flow to deliver nutrients and oxygen to their polyps while sweeping away waste products and preventing detritus from settling on the delicate branches. A random or surge-style flow pattern will promote healthy polyp extension and encourage robust, natural growth.
Placement & Growth
-
Placement: Best placed in the upper zones of your aquascape, close to the light source and in an area of strong water flow. Provide ample space between this coral and other SPS colonies, as Acropora can extend sweeper tentacles and engage in chemical warfare with neighboring corals. Aggressive or fast-growing corals may also overshadow or outcompete it.
-
Growth Rate: Acropora is a moderate-to-fast grower under optimal conditions. With stable parameters, intense lighting, and strong flow, you can expect steady branch extension and new growth tips regularly. A small frag will develop into an impressive, branching colony over time, creating a dramatic focal point in your reef.
Feeding & Nutrition
While Acropora derive a significant portion of their energy from photosynthesis through their symbiotic zooxanthellae, they are also active filter feeders that will benefit from supplemental feeding. Target feeding with fine particulate foods such as reef roids, amino acids, phytoplankton, or zooplankton once or twice per week will promote faster growth, healthier tissue, and more vibrant coloration. Maintaining stable nutrient levels (nitrate and phosphate) is also essential, as Acropora require some nutrients to thrive, but excessive levels can lead to browning or tissue damage.
Recommended Water Parameters
-
Temperature: 74–78°F (stability is critical)
-
Salinity: 1.024–1.026 (stable)
-
pH: 8.1–8.4
-
Alkalinity: 7–9 dKH (stability is essential)
-
Calcium: 420–450 ppm
-
Magnesium: 1280–1350 ppm
-
Nitrate: 1–5 ppm
-
Phosphate: 0.02–0.08 ppm
The Ultimate Addition for the Dedicated Reefer
Acropora Coral is the pinnacle of reef-keeping, rewarding dedicated aquarists with breathtaking coloration, elegant growth, and a dynamic presence that transforms any aquarium. While it requires stable conditions, intense lighting, and strong flow, the visual payoff is well worth the effort. Its vibrant colors and graceful branching structure make it a standout piece that will impress every viewer. Add this stunning SPS to your reef today and watch it grow into a magnificent centerpiece.
Important Handling Note: Handle Acropora with care, as their delicate branches can be brittle and prone to breakage. Always wear gloves when handling corals to protect both yourself and the specimen. Ensure your system is fully mature and stable before introducing SPS corals.
