Ultra Zoanthid Combo

Ultra Zoanthid Combo, Zoanthus spp. and related species, is a mixed colony of brightly colored colonial zoanthids featuring multiple contrasting color morphs on a single frag. This specimen displays vivid raspberry to magenta oral discs with fluorescent yellow-green skirts alongside intense red polyps with bright yellow centers, creating a dramatic multicolor combination.

Zoanthids grow as individual fleshy polyps connected by a shared mat of tissue. Each polyp features a central mouth surrounded by a broad oral disc and a ring of short tentacles forming the characteristic outer skirt. As the colony becomes established, new polyps develop from the connecting tissue and gradually spread across nearby hard surfaces.

The Ultra Zoanthid Combo is especially eye-catching because two distinctly different color patterns are growing together. The larger polyps display deep magenta-red centers with fine radial striping and bright yellow-green skirts, while the contrasting red morph shows intense scarlet coloration with bright yellow centers. Together they create a vibrant mixed-colony presentation under reef aquarium lighting.

Zoanthus species contain symbiotic photosynthetic dinoflagellates that provide much of their nutritional energy. They can also capture very small suspended food particles from the surrounding water. Stable water chemistry, moderate lighting, and gentle to moderate water movement generally support good polyp extension, coloration, and colony growth.

Because ornamental zoanthid trade names describe aquarium color morphs rather than scientifically distinct species, exact species identification cannot be determined reliably from coloration or external appearance alone. For this specimen, Zoanthus spp. and related species is the most appropriate scientific identification.

Care Guide

Scientific Identification: Zoanthus spp. and related species
Common Name: Zoanthids
Care Level: Easy to Moderate
Lighting: Low to Moderate
Water Flow: Low to Moderate, indirect and variable
Placement: Lower to middle areas of the aquarium depending on lighting intensity
Temperament: Semi-aggressive through growth and spreading; allow room from slower-growing neighboring corals
Reef Compatibility: Reef safe with appropriate placement
Feeding: Primarily photosynthetic; may also capture very small planktonic and particulate foods
Growth Form: Colonial polyps connected by a shared mat of tissue that spreads across hard substrate
Water Parameters: Maintain stable reef aquarium temperature and salinity with reasonably stable alkalinity and nutrient levels. Avoid rapid changes in water chemistry.
Special Considerations: Zoanthids can spread onto nearby rockwork as the colony expands. Moderate water movement helps prevent debris from settling between polyps. Handle zoanthids carefully and avoid contact with eyes, mouth, or broken skin because some zoanthids may contain palytoxin or related compounds. Gloves and eye protection are recommended when cutting or handling colonies.
