Size: 4.5 inches This Red Ribbon Double Symphyllia is "WYSIWYG" What you see is what you get so this one is yours! Symphyllia corals (commonly called closed brain corals) are large-polyp stony (LPS) corals known for their broad, fleshy tissue and meandering valleys that form a brain-like pattern across their surface. They often display rich, vibrant colors such as reds, greens, pinks, and multi-tone combinations with contrasting centers, making them a striking focal point in reef aquariums. Their thick tissue can expand significantly, giving them a soft, inflated appearance that adds movement and depth to the tank. For care, Symphyllia corals prefer low to moderate lighting and low, gentle water flow to allow their fleshy tissue to expand without stress or damage. They thrive in stable water conditions (temperature ~76–80°F, salinity ~1.025, alkalinity 8–9 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm) and can be sensitive to rapid parameter changes. Placement on the sand bed or lower rockwork is ideal to prevent irritation or tearing of their tissue. While they receive much of their energy from photosynthesis, they benefit from occasional feeding of small meaty foods like mysis shrimp or reef blends, which can promote growth and enhance coloration.
