Blue People Eater Zoas

About this coral

Blue People Eater Zoas are a type of zoanthid/palythoa coral commonly sold as colorful, fast-growing polyp colonies for reef aquariums. In practice, they’re used as showpiece “button polyp” corals that add movement and color on live rock or frag plugs, while benefiting from stable lighting and reasonable water flow. Zoanthids are also photosynthetic and rely largely on light, with supplemental nutrition from dissolved organic matter in well-maintained tanks.

Features:

• Polyps form dense colonies that can expand over time under suitable conditions
• A popular choice for reef displays because they create high-impact, living color on rockwork
• Tolerant of typical aquarium conditions when kept in stable, established saltwater systems
• Generally prefers moderate lighting and gentle-to-moderate water movement to keep polyps extended
• Naturally benefits from clean, nutrient-supported water—especially from dissolved nutrients and light
• Best kept on a secure base (rock or plug) so the colony can stabilize and grow where it’s placed
