Zoanthus sp.-Bloodshot Zoanthid is a widely coveted and highly unique addition for any Zoanthid enthusiast. Lush and velvety shades of green surround the outer portion of the tentacles, followed by an inner circle of rich red, and a signature dark slash through the center. These zoanthids look their best in medium to high lighting and moderate flow. As with all Zoanthid and Palythoa corals, great caution should be taken when handling these beauties, as many carry a potent toxin which can be life-threatening if exposed to the bloodstream.
