Purple Death Palythoa

Palythoa, often called "Palys," are colorful, fast-growing soft corals closely related to Zoanthids. They are known for their larger polyps, thicker flesh, and unique patterns, often featuring metallic or iridescent colors. Found in Indo-Pacific reefs, they are hardy and adaptable, making them an excellent choice for both beginners and experienced reef keepers.

Care Guide:

• Tank Size: Suitable for nano (10+ gallons) and larger reef tanks.
• Temperament: Moderate aggression – while they lack sweeper tentacles, they can release toxins and overgrow nearby corals if not managed.
• Lighting: Low to moderate (PAR 80-200); can adapt to higher light but may change coloration.
• Flow: Moderate to high – helps keep detritus off polyps and encourages healthy extension.
• Placement:
  • Best placed on rockwork or frag racks, ensuring space for controlled spreading.
  • Can also be placed on isolated islands to prevent them from overtaking other corals.
• Feeding:
  • Primarily rely on photosynthesis via their zooxanthellae.
  • Can benefit from target or broadcast feeding with reef amino acids, phytoplankton, or powdered coral foods to enhance growth and coloration.
• Water Parameters:
  • Temperature: 74-78°F (23-26°C)
  • pH: 8.1-8.4
  • Salinity: 1.024-1.026
  • Alkalinity: 8-12 dKH
  • Calcium: 400-450 ppm
  • Magnesium: 1250-1350 ppm
  • Nitrate & Phosphate: Low but detectable (NO₃: 5-10 ppm, PO₄: 0.02-0.07 ppm) – too much can encourage algae growth, too little can stunt coral health.
• Compatibility:
  • Moderate aggression, as they can overgrow other corals.
  • Best kept with other soft corals or in dedicated sections of a reef tank.
  • Avoid placement near sensitive SPS or LPS corals, as they may outcompete them.

Special Considerations:

• Palytoxin Warning: Some Palythoa species contain palytoxin, a potent toxin that can be dangerous if inhaled or comes into contact with open wounds. Always wear gloves and eye protection when handling, fragging, or scrubbing Palythoa colonies, and ensure proper ventilation.

Summary:

Palythoa corals are hardy, fast-growing, and visually striking soft corals that add bold colors and movement to reef tanks. With stable water conditions, moderate flow, and occasional feeding, they will thrive and create lush colonies. However, reef keepers should handle them with caution due to potential toxin exposure.
