Cyphastrea Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Cyphastrea corals (Cyphastrea species) are hardy large polyp stony corals admired for their encrusting growth patterns and vibrant coloration. Their dense, star-like polyps give a sparkling appearance that makes them a favorite among both beginner and advanced reef keepers. With low to moderate lighting, gentle flow, and minimal feeding needs, Cyphastrea thrive in a variety of reef aquariums.

Scientific Name & Identification

Cyphastrea corals (Cyphastrea species) are identifiable by their encrusting growth and tightly packed polyps that resemble tiny starbursts. Colonies come in a wide variety of colors, including orange, red, green, blue, and purple, often with contrasting polyp centers. Popular strains such as “Meteor Shower” and “Jingle Bells” are highly prized for their unique, eye-catching patterns.

Natural Habitat

Cyphastrea corals are native to the Indo-Pacific, where they grow across shaded reef slopes, lagoon areas, and rocky reef structures. Their preference for lower light environments makes them especially suitable for shaded or less illuminated areas in aquariums.

Aquarium Care & Setup

Temperature: 74–80°F (23–27°C)

pH: 8.1–8.4

Salinity: 1.024–1.026

Flow: Moderate, enough to keep detritus from settling while allowing polyps to remain fully extended

Lighting: Low to moderate, ideally 30–100 PAR. Avoid direct high-intensity light to prevent fading or bleaching

Placement: Rockwork or vertical surfaces, often in shaded or lower-light areas of the tank

Feeding Cyphastrea Corals

Cyphastrea corals rely primarily on photosynthesis but will benefit from occasional supplemental feeding. Target feeding with fine particulate coral foods such as reef roids or microplankton 1–2 times per week can encourage growth and enhance coloration.

Growth and Behavior

Cyphastrea corals encrust across rockwork and other surfaces, forming colorful mats that expand steadily over time. They are peaceful corals without long sweeper tentacles, making them excellent neighbors in mixed reefs. Polyps remain extended throughout the day and night, giving the coral its signature “starry night” appearance.

Tankmates

Cyphastrea corals are compatible with most peaceful reef fish and invertebrates. Avoid placing them near overly aggressive corals that might overgrow them. Ideal tankmates include clownfish, gobies, wrasses, cleaner shrimp, and snails.

FAQs about Cyphastrea Corals

Are Cyphastrea corals easy to keep?

Yes, they are hardy and adaptable, making them suitable for both beginners and experienced aquarists.

Do Cyphastrea corals need to be fed?

Not strictly, but occasional feeding with fine coral foods once or twice per week improves growth and coloration.

What lighting do Cyphastrea corals need?

Low to moderate lighting (30–100 PAR). Too much light can cause fading or bleaching.

Where should I place Cyphastrea corals in my tank?

On rockwork or vertical surfaces, often in shaded areas with moderate flow.

Will Cyphastrea corals sting other corals?

No, they are peaceful and do not extend long sweeper tentacles.

How fast do Cyphastrea corals grow?

They grow at a moderate pace, steadily encrusting across available rockwork and surfaces.

Conclusion

Cyphastrea corals (Cyphastrea species) are hardy, colorful, and peaceful LPS corals that bring texture and vibrancy to reef aquariums. Their encrusting growth makes them perfect for filling in rockwork, while their adaptability makes them one of the easiest corals to keep. With stable water conditions, moderate flow, and subdued lighting, Cyphastrea thrive and add lasting beauty to any reef.
