Ultra Rainbow Open Brain Coral (Trachyphyllia sp.) – Intense Color and Flowing Form
The Ultra Rainbow Trachyphyllia is a premium large polyp stony (LPS) coral, celebrated for its incredible multi-color patterns and fleshy, flowing appearance. With its bold mix of reds, greens, blues, and yellows, this “Ultra” grade coral is a true showpiece that instantly draws attention in any reef aquarium.
Exceptional Rainbow Coloration
This coral features a stunning blend of vibrant colors that can include neon green, deep red, bright orange, and electric blue, often arranged in swirling or striped patterns across the large polyp surface. Each specimen is unique, with “Ultra” varieties selected for their especially intense and contrasting coloration.
Under proper lighting, these colors become even more vivid, creating a glowing centerpiece effect.
Large, Fleshy Polyp with Flowing Movement
Trachyphyllia corals form a single large polyp with a fleshy, inflated body that expands during the day. Gentle water movement causes the tissue to sway slightly, adding a soft, natural motion to the aquarium.
Its open brain-like structure gives it both texture and visual depth, making it ideal as a focal coral.
Easy to Moderate Care
This species is generally considered suitable for most aquarists, including those with some experience in LPS corals. It prefers stable water parameters and does best in moderate lighting with low to moderate flow.
Too much flow can cause the tissue to retract, while too little may lead to debris settling on the coral.
Feeding and Growth
While photosynthetic, Trachyphyllia benefits greatly from occasional feeding. Offering small meaty foods such as mysis shrimp or finely chopped seafood can enhance growth, coloration, and overall health.
Feeding responses are usually strong, with the coral extending feeding tentacles, especially in the evening.
Placement and Compatibility
This coral should be placed on the الرمل (sand bed) or a flat, stable surface where its tissue will not be damaged. It should be given space from other corals, as its fleshy tissue can be sensitive and may be damaged by contact or aggression.
A True Showpiece Coral
The Ultra Rainbow Trachyphyllia is perfect for aquarists looking to create a centerpiece coral with maximum visual impact. Its combination of vibrant color, flowing form, and relatively manageable care makes it one of the most desirable LPS corals available.
