Overview & Characteristics

A hardy Large Polyp Stony (LPS) coral known for fleshy bright green polyps, tubular branches, and enthusiastic feeding behavior.

Water Parameters & Environment

Stable water parameters are critical for long-term health. Avoid rapid fluctuations in temperature and pH when performing routine water changes.

  • Temperature: 75–80°F (24–27°C)
  • pH Range: 8.1–8.4
  • Water Type: Saltwater (Specific Gravity 1.025)

Evaluate whether your current aquarium chemistry matches these thresholds with our free Water Parameter Safety Checker or calculate water replacement with the Water Change Calculator.
