Grand Master Krak Zoas

About this coral

Grand Master Krak Zoas are zoanthid-type “zoa” polyps sold for reef aquariums. Used as colorful, living soft-coral colonies, they add compact, mat-forming growth and vibrant polyps to established tanks. Because the exact scientific species for “Krak Zoas” isn’t provided here, this listing is best treated as group-level zoanthid (Zoanthids & Palys) care guidance.

Features:

• Attractive polyp display for reef aquascapes, often appreciated for the way individual polyps “pop” within a colony
• Zoanthids are generally hardy for beginners when basic reef stability is maintained
• Helpful in refugium or frag-reef style setups where moderate lighting can support photosynthesis
• Colonies can gradually expand across suitable substrate or on rock surfaces under stable conditions
• Typically benefit from gentle, indirect water movement rather than strong blasting flow
• In many reef systems, they rely mainly on light while also benefiting from dissolved organics in the water
• Best kept in an established aquarium with consistent parameters rather than frequently changing water chemistry

Specifications:

• Care level: Moderate (general zoanthid group guidance)
• Lighting: Moderate to high reef lighting (group guidance)
• Water flow: Moderate, indirect circulation (group guidance)
• Placement: Near the rockwork where light reaches the polyps and flow is not directly forceful
• Diet: Photosynthesis-supported; benefits from dissolved organics in reef water
• Temperature: About 72–78°F (group guidance)
• pH: About 8.1–8.4 (group guidance)
• Salinity: About 1.024–1.026 specific gravity (group guidance)
• Alkalinity: Roughly 7–12 dKH (group guidance)
• Calcium: Roughly 400–450 ppm (group guidance)
• Magnesium: Roughly 1200–1350 ppm (group guidance)
