Ultra Trachyphyllia Coral

Introduction to Trachyphyllia

Trachyphyllia, commonly known as Open Brain Corals or Trachys, are a type of Large Polyp Stony (LPS) coral admired for their vibrant colors and fleshy, rounded structure. They come in a range of stunning shades, including green, red, purple, and blue, often with unique patterns or gradients that make each one distinctive.

These peaceful reef inhabitants are moderately easy to care for and thrive in stable tank environments. Their bold appearance and adaptability make them a favorite for aquarists looking to add a striking focal point to their aquarium.

Natural Habitat and Origin

Open Brain Corals are native to the Indo-Pacific, with populations found in regions like Australia, Indonesia, and the Great Barrier Reef. They are typically found resting on sandy substrates or nestled among rocks in lagoons and protected reef slopes.

In their natural environment, these LPS specimens thrive in calm, nutrient-rich waters where they can expand their fleshy polyps without disruption. Their preference for low-flow habitats makes them an excellent addition to aquariums designed to mimic these conditions.

Water Chemistry

Maintaining the right water chemistry is essential for the health and vibrant coloration of Open Brain Corals. These LPS corals are particularly sensitive to sudden parameter swings, so a stable environment is crucial. Trachyphyllia tend to do best in mature reef systems where water conditions remain consistent and predictable.

Ideal Parameters:

• Calcium: 400–450 ppm
• Alkalinity: 8–12 dKH
• Magnesium: 1250–1350 ppm
• Nitrates: 5–15 ppm
• Phosphates: <0.10 ppm
• Temperature: 76–80°F
• Salinity: 1.024–1.026

While Trachys are slightly more tolerant of elevated nutrient levels than some other corals, poor water quality or imbalances can quickly result in stress or tissue recession. Regular water changes and careful monitoring are recommended to maintain optimal conditions.

Lighting

Trachyphyllia corals are well-suited to low to moderate lighting conditions, thriving in areas with a PAR range of 50–150. These corals naturally inhabit shaded or semi-shaded regions in the wild, making them ideal for placement in the lower or more sheltered areas of your tank.

Best Practices for Lighting:

• Start by placing your Trachy in a shaded or low-light area and gradually acclimate it to brighter conditions over 2–3 weeks.
• Blue-spectrum lighting enhances the coral's fluorescent tones, bringing out intricate patterns and vibrant hues.
• Avoid overly intense light, which can cause bleaching or tissue stress.

At Top Shelf Aquatics, we house Open Brain Corals under advanced lighting systems, such as Ecotech Marine Radions and T5 fixtures, designed to replicate natural conditions. This ensures optimal health and brings out the coral’s bold coloration.

Water Flow

Proper water flow is essential for the health of Trachyphyllia, as it aids in removing waste, delivering nutrients, and preventing debris accumulation on their fleshy tissue. They thrive in low to moderate water movement, allowing their large polyps to expand fully without being disturbed by strong currents.

Key Considerations for Flow:

• Gentle, indirect flow is ideal to keep the coral’s surface clear of debris while avoiding tissue damage.
• Avoid high-flow areas, which can cause the coral to retract its polyps or experience irritation.
• Placement on a flat, stable surface or sandy substrate ensures the coral remains undisturbed by shifting water currents.

At Top Shelf Aquatics, we use advanced flow systems like Ecotech Marine MP pumps to mimic the calm, steady water movement found in natural lagoon environments. These setups support healthy tissue expansion and feeding behavior.

What We Feed

Trachyphyllia corals primarily rely on their symbiotic zooxanthellae for energy through photosynthesis, but supplemental feeding provides additional nutrients that enhance their coloration, growth, and overall health. They benefit greatly from occasional target feeding, especially in systems with low nutrient levels.

Recommended Foods:

• Mysis shrimp
• Finely chopped seafood, such as scallops or squid
• High-quality powdered foods like Reef Roids or Benepets Coral Food
• Plankton-based options, including Tisochrysis

Feeding Tips:

• Target-feed the coral by gently delivering food near its central mouth using a pipette or turkey baster.
• Feeding during the evening, when the coral’s feeding tentacles are extended, is most effective.
• Pause water movement for 10–15 minutes to give the coral time to capture and consume its meal.

Coloration and Tank Maturity

Trachyphyllia are renowned for their striking coloration, with hues ranging from metallic greens and fiery reds to purples and blues. Many specimens feature intricate gradients or marbled patterns that become even more pronounced under blue-spectrum lighting.

Open Brain Corals tend to thrive in mature reef systems where water quality is stable and nutrient levels are balanced. In newer tanks, fluctuating parameters can lead to stress, slowing growth or diminishing the coral's natural brilliance.

Common Challenges

• Tissue Recession: Poor water quality, unstable parameters, or physical damage can lead to tissue loss.
• Bleaching: Excessive light exposure or sudden changes in lighting conditions can cause bleaching.
• Polyp Bailout: Extreme stress can result in polyp bailout, where the coral detaches from its skeleton.
• Detritus Accumulation: Gentle water flow helps keep their fleshy surface clean and free of debris.
• Pests and Aggression: Aggressive tank mates or pests may harm Trachyphyllia by nipping at their tissue.

Acclimation Guide

Proper acclimation ensures Trachyphyllia adjust smoothly to their new environment:

• Temperature Acclimation: Float the sealed bag in your aquarium for 15–20 minutes to equalize the temperature.
• Drip Acclimation: Gradually mix tank water with the shipping water over 30–45 minutes.
• Lighting Acclimation: Place the coral in a shaded or low-light area initially and gradually increase exposure.
• Placement: Position Trachyphyllia on a stable, flat surface or sandy substrate in a low to moderate flow area.
