Ruby Grapefruit and Super Tangerine Zoanthid Combo Coral Frag

Ruby Grapefruit and Super Tangerine Zoanthid Combo, Zoanthus sp., is a mixed colony of brightly colored zoanthids selected for contrasting multicolor patterns and mat-forming growth. This WYSIWYG coral frag combines deep ruby to magenta polyps with yellow-green skirts alongside vivid tangerine-orange polyps with green outer tentacles. The contrasting color morphs create a highly decorative mixed colony on a single frag. Zoanthus polyps are connected by a common 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 can also capture suspended organic matter and very fine foods. Because species-level identification within Zoanthus cannot be determined reliably 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.
