Zoanthus spp. (Ultra Grade) are highly sought-after soft polyps prized for their vivid colours and dynamic appearance in marine reef aquariums. This Ultra Grade variant offers superior colour vibrancy and polyp density, making it a premium choice for hobbyists seeking to enhance their reef displays.
These corals are tank-bred, ensuring better acclimation to captive conditions and reducing wild collection impact. Their tiny size makes them ideal for aquarists looking to cultivate a dense mat or cluster of polyps.
Care and Husbandry
- Lighting: Moderate to high lighting is recommended, such as LED or T5 fixtures, to support photosynthesis and maintain vibrant colours.
- Water Flow: Moderate, indirect water flow helps keep the polyps clean without causing excessive stress.
- Placement: Position on rockwork or frag plugs where they can spread without immediate competition. Provide adequate spacing from aggressive corals to avoid stinging or overgrowth.
- Water Parameters: Maintain stable reef conditions: temperature 24-26°C, salinity 1.023-1.025, pH 8.1-8.4, and low nutrient levels.
- Feeding: Primarily photosynthetic but benefit from occasional feeding of microplankton or coral-specific liquid foods.
Compatibility and Reef Safety
Zoanthus spp. are generally reef safe with adequate spacing. They coexist well with most peaceful reef inhabitants but should be monitored to prevent overgrowth on neighbouring corals. Caution is advised as some Zoanthids can produce palytoxin; handle with care and use gloves when fragging.
Additional Notes
Due to the genus-level identification, care recommendations are conservative to ensure success across various Zoanthus morphs. Regular observation and water quality maintenance are key to thriving colonies.
