The Bicolor Open Brain Coral (Trachyphyllia geoffroyi)

The Bicolor Open Brain Coral (Trachyphyllia geoffroyi) is a large polyp stony (LPS) coral known for its brilliant color contrasts and distinctive, fleshy brain-like folds. With striking bicolor patterns — often featuring greens, reds, oranges, and purples — this coral adds an impressive splash of color and motion to reef aquariums.

Open Brain Corals are hardy and relatively easy to care for, thriving under low to moderate lighting and gentle to moderate water flow. They are best placed on sandy substrate or flat rockwork, allowing their tissue to expand fully without damage. Semi-aggressive in nature, they should be given space from neighboring corals.

This coral benefits from occasional direct feeding of meaty foods such as mysis shrimp, krill, or enriched brine shrimp, which enhances growth and maintains vibrant coloration. With proper care and stable water parameters, the Bicolor Open Brain Coral will become a long-lasting centerpiece, admired for both its beauty and resilience.
