Platygyra Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Platygyra corals (Platygyra species), commonly known as Brain Corals, are prized for their intricate maze-like skeletal structures and fleshy polyps. Their striking texture and color make them a centerpiece in reef aquariums. With moderate care, they thrive and slowly expand to form beautiful, textured colonies.

Scientific Name & Identification

Platygyra corals belong to the family Merulinidae and are characterized by winding valleys and ridges formed by closely packed polyps. Colonies are encrusting to dome-shaped and display colors ranging from green and brown to orange and pink. Unlike Lobophyllia or Favia, Platygyra have more uniform valleys with consistent meandering patterns.

Natural Habitat

In the wild, Platygyra inhabit shallow to mid-depth Indo-Pacific reefs, often in moderate water flow environments. Their natural habitat informs optimal aquarium placement for growth and polyp expansion.

Aquarium Care & Setup

Platygyra corals require stable water parameters and moderate conditions:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.024–1.026

• Flow: Low to moderate to allow full polyp expansion

• Lighting: Moderate (50–150 PAR), acclimate gradually

• Placement: Lower to mid-level rockwork or sandbed with spacing from neighbors

Feeding

Although primarily photosynthetic, Platygyra respond well to target feeding. Small meaty foods such as mysis shrimp, brine shrimp, or coral-specific pellets 2–3 times per week improve growth, coloration, and polyp extension. Feeding is most effective during night or low-light periods.

Growth and Behavior

Platygyra grow moderately, forming encrusting or dome-shaped colonies with maze-like valleys and ridges. They are aggressive, extending sweeper tentacles at night for defense. Their polyps create a dynamic, textured surface that adds depth and movement to a reef display.

Tankmates

Peaceful reef fish such as gobies, clownfish, wrasses, and tangs are ideal companions. Avoid aggressive coral-nipping species. Ensure neighboring corals are spaced to avoid contact with sweeper tentacles.

Conclusion

Platygyra corals are visually striking and moderately hardy LPS corals that add intricate texture and color to reef aquariums. With moderate lighting, gentle flow, stable water parameters, and occasional feeding, they thrive and form beautiful encrusting or domed colonies, making them a rewarding addition for beginner and experienced reef keepers alike.
