A hardy SPS coral with densely packed small polyps. Grows in low light, recommended for beginners.
Cyphastrea (family Merulinidae) is a genus of encrusting to hemispherical SPS corals found on Indo-Pacific reef slopes and beneath overhangs. Their surface is densely patterned with small, rounded corallites that give colonies a distinctive granular texture. Uniquely among SPS, Cyphastrea tolerates a broad lighting range of 50–200 PAR, allowing placement in shaded reef zones where other small-polyp corals struggle. Color variants in green, red, orange, and purple are available; intensely fluorescent specimens command collector premiums. Growth is deliberate but consistent, gradually encrusting surrounding rock. Low to moderate care requirements and shade tolerance make Cyphastrea one of the most versatile SPS options for mixed reef displays.

The Cyphastrea lives 10+ years.
The Cyphastrea grows to 5-20cm.
The ideal water temperature for the Cyphastrea is 24〜27℃.
Gentle to moderate indirect flow and stable parameters (24–27°C, KH 8–10, Ca 400–430 ppm) suit them well.

Photosynthesis
It tolerates lower light than typical SPS and grows across a wide 50-200 PAR range. One of the few SPS that can be placed in shaded areas.
Low to moderate flow is suitable; it dislikes strong direct current. It can also be placed in dim spots such as under overhangs.
Keep 24-27°C with KH 8-10 and Ca 400-430 ppm. Growth is slow but steady as it encrusts over the rock.
Spreads by encrusting
One of the hardiest SPS, with low to moderate difficulty. Fragging is easy, so even beginners can propagate it.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Cyphastrea is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Cyphastrea is 10+ years. With proper care and nutrition, they can live a long and healthy life.
Cyphastrea typically reaches 5-20cm as an adult. Size may vary depending on care conditions and individual genetics.
Cyphastrea feeds on: Photosynthesis. Aim for a balanced diet with appropriate feeding frequency.
