Psammocora Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Psammocora corals (Psammocora species) are delicate encrusting corals valued for their small, closely packed polyps and textured colonies. Often mistaken for small Favia or Cyphastrea species or other encrusters, they are distinct for their numerous small fuzzy polyps.

Scientific Name & Identification

Psammocora corals belong to the family Psammocoridae and can be recognized by their tightly packed, small polyps and fuzzy, encrusting colonies. Unlike Faviidae corals, Psammocora polyps are smaller and more uniform, and colonies spread in a more continuous sheet rather than forming domed or boulder-like structures. Colors range from muted greens and browns to soft oranges, yellows, and purples.

Natural Habitat

These corals inhabit reef slopes and lagoon areas across the Indo-Pacific, where water flow is moderate and surfaces are hard enough for encrusting growth. Their natural environment informs aquarium placement and flow requirements.

Aquarium Care & Setup

Psammocora corals thrive under stable conditions:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.024–1.026

• Lighting: Moderate (50–150 PAR)

• Flow: Low to moderate; sufficient to prevent detritus buildup

• Placement: Lower or mid-level rockwork or sandbed with space to expand

Feeding

Although photosynthetic, Psammocora benefit from occasional feeding. Target feeding with mysis, brine shrimp, or fine coral pellets 2–3 times per week encourages faster growth and enhances coloration. Polyps are most receptive during the night or low-light periods.

Growth and Behavior

Psammocora form encrusting colonies that gradually expand across rock surfaces. They are semi-aggressive and extend sweeper tentacles to defend territory at night. Growth is moderate, making them suitable for mixed reef aquascapes without overwhelming neighbors.

Tankmates

Peaceful reef fish such as gobies, clownfish, and tangs are ideal companions. Avoid aggressive corals and coral-nipping fish that may damage polyps.

Conclusion

Psammocora corals are subtle yet fascinating encrusting corals that add texture and interest to reef tanks. With moderate lighting, gentle flow, stable water conditions, and occasional feeding, they thrive and provide long-term growth and aesthetic appeal.
