Green Star Polyps Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Star Polyps (Pachyclavularia species) are soft corals valued for their hardiness, rapid growth, and dynamic waving polyps. They create vibrant green, purple, or multicolored carpets in reef tanks, adding movement and filling empty rock surfaces quickly.

Scientific Name & Identification

Star Polyps belong to the family Clavulariidae and are identified by their encrusting mats with polyps that extend from a mat-like base. Polyps have a central mouth with radiating tentacles and often fluoresce brightly under actinic lighting. They are sometimes confused with similar clove polyps, but Star Polyps form faster-growing, larger carpets.

Natural Habitat

Star Polyps are native to the Indo-Pacific, thriving on reef flats, rubble zones, and shallow slopes with moderate water movement. Their natural habitat informs their adaptability and rapid colonization in home aquariums.

Aquarium Care & Setup

To maintain healthy Star Polyps:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.024–1.026

• Flow: Moderate, enough to encourage polyp extension

• Lighting: Moderate to high; higher intensity promotes spreading and polyp coloration

• Placement: Rockwork or substrate with room to spread and avoid smothering slower corals

Feeding

Star Polyps rely mostly on photosynthesis but benefit from occasional feedings of phytoplankton, reef roids, or fine powdered foods. Target feeding can enhance coloration and encourage faster spreading.

Growth and Behavior

These corals grow rapidly, forming thick, waving carpets. Polyps are extended almost continuously, creating movement and shimmer throughout the aquarium. They are semi-aggressive through space competition, so maintain proper spacing from slower-growing species.

Tankmates

Star Polyps are compatible with most reef-safe fish and other soft or hardy LPS corals. Ideal tankmates include clownfish, gobies, tangs, and cleaner shrimp. Avoid placing them near slow-growing or delicate SPS corals that may be smothered.

Conclusion

Star Polyps are beginner-friendly, fast-growing soft corals that add color, movement, and life to reef tanks. Their adaptability and minimal care requirements make them perfect for filling rockwork and creating vibrant coral carpets. With proper lighting, moderate flow, and occasional feeding, Star Polyps thrive and rapidly enhance any reef display.
