Cyphastrea
Cyphastrea is an SPS (small polyp stony) coral whose colonies are made up of countless tiny, densely packed polyps. It's hardy, tolerant of fluctuating conditions, and grows well even under relatively low lighting, which makes it a practical choice for anyone new to coral keeping. Like other photosynthetic corals, it hosts symbiotic algae and draws energy from your tank's lighting. Watching the colony gradually spread, along with the subtle variation in color and texture between individuals, is part of the appeal. It's also a coral you can expect to keep for the long haul.

About Cyphastrea
Cyphastrea is a hardy SPS coral with densely packed small polyps that thrives even in low light, making it a great pick for beginners. It typically lives 10+ years and reaches 5-20cm as an adult.
7 things to know before welcoming a Cyphastrea
1Lighting Requirements
Cyphastrea tolerates low light, so intense lighting isn't required, but consistent daily exposure supports healthy growth. Introduce it gradually to new lighting conditions to avoid shocking the coral.
2Water Quality & Flow
Though hardy, Cyphastrea is sensitive to sudden shifts in water parameters. Moderate water flow helps the polyps open fully and take in light and nutrients efficiently.
3Placement in the Tank
Colonies spread outward as they grow, so leave space away from other corals. Plan your aquascape with the adult size (5-20cm) in mind from the start.
4Temperament & Compatibility
Cyphastrea is relatively peaceful, but as it grows it can sting neighboring corals it comes into contact with. Keep adequate spacing between colonies to avoid conflict.
5Signs of Good Health
Fully extended polyps are the best indicator of health. Shrinking polyps, bleaching, or excess mucus signal that water quality or lighting needs adjustment.
6Feeding
Photosynthesis provides most of its energy, so feeding isn't essential, but occasional feeding with fine plankton-sized food can support growth. Overfeeding can degrade water quality, so keep it sparing.
7Before You Bring One Home
Introduce Cyphastrea only after your tank is fully cycled and stable. A careful acclimation process, such as drip acclimation, helps reduce stress from the transition.
Frequently asked questions about Cyphastrea
- Q.Is Cyphastrea suitable for beginners?
- A.Yes, Cyphastrea is hardy and tolerates low light, making it a good choice for first-time coral keepers. Maintaining stable, basic water quality is the key to long-term success.
- Q.How large does it grow?
- A.Adult colonies typically reach 5-20cm. Since it spreads outward as a colony, give it enough surrounding space when placing it in your tank.
- Q.Does it need to be fed?
- A.Feeding isn't essential since photosynthesis provides most of its energy. Occasional feeding with fine plankton-sized food can help support growth.
- Q.Can it be kept with other corals?
- A.It's relatively peaceful, but once it grows large enough to touch neighboring corals, it can sting them. Keep adequate spacing between colonies to avoid conflict.
- Q.How long does it typically live?
- A.With proper care, Cyphastrea can live 10 years or more. Maintaining stable water quality and consistent lighting is key to keeping it long-term.
