Description
Symphyllia, often called a “brain coral,” is a large-polyp stony (LPS) coral known for its fleshy tissue and maze-like ridges and valleys. It displays rich, vibrant colors such as red, green, orange, and pink, often with contrasting patterns. Its bold appearance and slow, flowing movement make it a stunning centerpiece in reef aquariums.
