Ruby Grapefruit and Magician Combo Zoanthids Coral Frag

Ruby Grapefruit and Magician Combo Zoanthids, Zoanthus sp., are colonial zoanthids featuring two distinct color morphs combined on a single WYSIWYG coral frag. This specimen displays vivid ruby-red polyps with bright green centers alongside larger grapefruit-toned polyps with deep magenta to burgundy oral discs and contrasting yellow-green skirts. The combination creates strong color contrast and visual variety in one colony. Zoanthus polyps grow from a shared tissue mat and can gradually spread across adjacent rockwork under favorable reef conditions. They contain symbiotic zooxanthellae that provide much of their energy through photosynthesis, while the polyps may also capture suspended organic material and fine particulate foods. Because exact species identification within Zoanthus cannot be reliably determined from external appearance alone, Zoanthus sp. is the most scientifically appropriate designation for this specimen.

Care Guide: Zoanthus sp. generally performs well under low to moderate reef lighting with moderate, indirect water flow. Provide enough circulation to keep debris from settling between the polyps without preventing them from fully opening. Place the frag on stable rockwork with room for the colony to spread. Maintain stable salinity, temperature, alkalinity, calcium, magnesium, nitrate, and phosphate. Zoanthids are primarily photosynthetic but may benefit from dissolved nutrients and occasional fine particulate or planktonic foods. Because zoanthids may contain palytoxin or related compounds, avoid handling damaged tissue with bare hands and use appropriate eye and skin protection when cutting, fragging, or otherwise disturbing the colony.
