Exosphere Zoa

The Exosphere Zoanthid is a rare and highly sought-after Zoanthid morph, known for its dramatic contrast of deep black, electric red, neon orange, and bright yellow hues. Under actinic blue lighting, these zoas glow intensely, making them a premium addition to any reef tank. Like other Zoanthids, Exosphere Zoas are hardy, fast-growing, and an excellent choice for both beginner and advanced aquarists.

Care Guide:

• Tank Size: Suitable for nano (10+ gallons) and larger reef tanks.
• Temperament: Peaceful, does not have sweeper tentacles but can spread quickly and overgrow nearby corals.
• Lighting: Low to moderate (PAR 80-200); strong actinic lighting enhances their fluorescent colors.
• Flow: Moderate to high – prevents detritus buildup and encourages full polyp extension.
• Placement:
  • Best placed on rockwork or frag racks, ensuring it has room to spread.
  • Can also be placed on isolated islands to prevent overgrowth in the main reef.
• Feeding:
  • Primarily relies on photosynthesis via their zooxanthellae.
  • Benefits from broadcast feeding of:
    • Reef amino acids
    • Phytoplankton
    • Powdered coral foods (e.g., Reef Roids)
• 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) – excess nutrients can encourage algae growth, while too little can stunt growth.

Compatibility:

• Very peaceful, can be placed near most corals.
• Best kept with other soft corals or LPS corals that do not compete aggressively.
• Avoid placement near aggressive corals with strong sweeper tentacles (e.g., Galaxea, Torch, Hydnophora).

Special Considerations:

• Overgrowth Management: Exosphere Zoas can spread rapidly, so placing them on an isolated rock can help control their growth.
• Coloration Enhancement: Their deep blacks, fiery reds, and neon accents appear most vibrant under blue-heavy spectrum lighting.
• Palytoxin Warning: Like many Zoanthids, they may contain palytoxins, which can be toxic if inhaled or handled improperly. Always wear gloves and eye protection when fragging or handling.

Summary:

The Exosphere Zoanthid is a rare, high-end, and visually stunning soft coral, perfect for creating a dramatic, glowing reefscape. With stable water conditions, moderate flow, and occasional feeding, it will thrive and develop into a breathtaking colony in any reef aquarium.
