CB Angel Eye Favia Coral

Introduction to Favia Corals

Favia corals, often referred to as closed brain corals, are a captivating addition to reef aquariums, admired for their fleshy polyps and distinctive patterns. These Large Polyp Stony (LPS) corals are available in a variety of vibrant colors, including shades of green, red, and gold, often featuring intricate ridges and grooves that resemble a brain-like structure.

Renowned for their resilience, Favia corals are an excellent choice for reef enthusiasts of all levels. Their moderate growth rate and compatibility with diverse tank setups make them a versatile and visually striking option for aquascaping.

Location

Native to the vibrant reefs of the Indo-Pacific, Favia species are commonly found thriving in sheltered areas along reef slopes and lagoons. These regions often have moderate water movement and nutrient-rich conditions that support their growth and vibrant coloration.

In the wild, these corals encrust rock structures and rubble, forming domes or expansive mats as they grow. Their adaptable nature allows them to settle in various light and flow conditions, making them a versatile addition to reef aquariums.

Water Chemistry

Favia corals are relatively hardy and can tolerate slight fluctuations in water parameters, though maintaining stable conditions is crucial for optimal health and vibrant coloration. Recommended water chemistry ranges:

• Calcium: 380–450 ppm
• Alkalinity: 8–9.5 dKH
• Magnesium: 1250–1350 ppm
• Nitrates: 5–15 ppm
• Phosphates: <0.10 ppm
• Temperature: 75–80°F
• Salinity: 1.024–1.026

These corals thrive in nutrient-balanced systems, where regular testing and adjustments help maintain consistent parameters. While they are forgiving of minor swings, providing a stable environment encourages steady growth and enhances their vibrant coloration.

Lighting

Favia corals thrive under moderate lighting conditions, with an ideal PAR range of 80–150. This supports their photosynthetic zooxanthellae while avoiding stress or bleaching.

They are best placed in lower to middle sections of the tank, where indirect light mimics their natural habitat on reef slopes and lagoons. Gradual acclimation to new lighting conditions is essential to prevent stress or tissue damage.

At Top Shelf Aquatics, we use a combination of Ecotech Marine Radions and metal halides to create balanced lighting conditions that promote healthy growth and rich coloration for our Favia specimens.

Water Flow

Favia corals prefer moderate, steady water flow, which helps keep their fleshy polyps clean while ensuring proper nutrient delivery. Gentle currents are ideal to prevent debris accumulation without overwhelming the coral’s structure.

At Top Shelf Aquatics, we replicate natural reef conditions using a combination of Ecotech Marine MP’s, Reef Octopus Octo Pulse, and Sicce XStream wave makers. These dynamic flow patterns support the health and longevity of Favia corals in our aquaculture systems.

What We Feed

Favia corals derive much of their energy from their symbiotic zooxanthellae, but supplemental feeding can greatly enhance their growth and coloration. They consume fine-particle foods and benefit from occasional feedings of meatier options like mysis shrimp.

At Top Shelf Aquatics, we provide Favia corals with a nutrient-rich diet, including our signature Royal Flush blend, which contains:

• Tisochrysis
• Rhodomonas
• Tetraselmis

Additionally, products like Reef Roids and Benepets supply fine particles, while mysis shrimp, offered once or twice a month, provides a protein boost. Feed them 2–3 times a week using broadcast feeding or a turkey baster for targeted feeding. Pause water flow for 10–15 minutes to allow the coral to absorb nutrients effectively.

Coloration and Tank Maturity

Favia corals are celebrated for their vivid coloration, often displaying shades of green, red, gold, and even multi-color combinations. Maintaining these hues requires stable water
