Zoanthids are a type of coral that belong to the family Zoanthidae. They are popular among reef aquarium enthusiasts due to their vibrant colors and relatively easy care requirements. Here are the general requirements for keeping zoanthid corals:
1. Water Parameters:
– Temperature: Zoanthids prefer a stable water temperature between 72°F and 78°F (22°C to 26°C).
– Salinity: Maintain a specific gravity or salinity level of 1.024 to 1.026.
– pH: The pH level should be within the range of 8.1 to 8.4.
– Alkalinity: Zoanthids thrive in a stable alkalinity range of 8 to 12 dKH (or 143 to 214 ppm).
2. Lighting:
– Zoanthids require moderate to high lighting levels. LED lights or metal halide fixtures are commonly used in reef aquariums to provide the necessary light intensity. Aim for a light spectrum that includes blue and white light to enhance their colors.
3. Water Flow:
– Zoanthids prefer moderate water flow. You can achieve this by using powerheads or wavemakers to create gentle water movement in the aquarium. Avoid placing them in areas with high turbulence, as it may damage their delicate tissues.
4. Water Quality:
– Maintain excellent water quality by regularly testing and monitoring the parameters mentioned above. Regular water changes, around 10% every 1 to 2 weeks, help keep the water quality stable and remove accumulated impurities.
5. Feeding:
– Zoanthids are photosynthetic organisms and derive a significant portion of their nutrition from the symbiotic algae (zooxanthellae) living within their tissues. They also benefit from occasional feedings of small, meaty foods. Offer them small pieces of mysis shrimp, cyclops, or other finely chopped marine foods once or twice a week.
6. Placement:
– Zoanthids can be placed on live rock, coral rubble, or the aquarium substrate. Ensure they have enough space to expand and grow without coming into direct contact with other corals, as some species can be aggressive and sting neighboring corals.
7. Acclimation:
– When introducing new zoanthids to your aquarium, it’s important to acclimate them slowly to avoid shocking them. Dip the coral in a coral dip solution to remove any pests or hitchhikers, and then gradually adjust the temperature, salinity, and lighting over a period of several hours before placing them in the tank.
Remember, while zoanthids are generally hardy corals, each species may have specific care requirements. It’s essential to research the particular type of zoanthid you have to ensure you provide the ideal conditions for its health and growth.
