Acanthophyllia donut corals are a popular addition to reef tanks, thanks to their stunning appearance and relatively easy care requirements. These corals are known for their large, circular polyps, which come in a range of vibrant colors, including green, blue, purple, and orange. In order to keep your Acanthophyllia donut coral healthy and happy in your reef tank, there are a few key care tips to keep in mind.

Water Quality:

The first and most important aspect of caring for Acanthophyllia donut coral is to ensure that your tank's water quality is top-notch. These corals are sensitive to changes in water temperature, pH, and salinity, so it's essential to monitor these parameters regularly using a high-quality test kit. Aim to keep your water temperature between 75 and 80°F, pH between 8.1 and 8.4, and salinity between 1.024 and 1.026.

Lighting:

Acanthophyllia donut corals require moderate to high lighting to thrive. If you're using LED lights, ensure that they're powerful enough to penetrate the depths of your tank and reach the coral. If you're using T5 or metal halide lights, you may need to adjust the intensity depending on the coral's placement in the tank. Aim for a PAR (photosynthetic active radiation) of around 150 to 250.

Placement:

When it comes to placing your Acanthophyllia donut coral in your reef tank, it's essential to choose a spot that offers the right conditions for the coral to thrive. These corals prefer moderate to high water flow, as this helps to ensure that they receive a steady supply of nutrients and oxygen. Avoid placing your coral in areas with strong, direct flow, as this can damage the delicate polyps.

Feeding:

Acanthophyllia donut corals are photosynthetic, which means that they obtain much of their energy from the light provided by your tank's lighting system. However, they also require regular feedings of small meaty foods, such as mysis shrimp, brine shrimp, or other small planktonic organisms. Offer food to your coral once or twice a week, ensuring that any uneaten food is removed from the tank to prevent water quality issues.

Maintenance:

Regular maintenance is essential to keep your Acanthophyllia donut coral healthy and happy. This includes weekly water changes of around 10% of your tank's total volume, as well as regular cleaning of your tank's equipment, including filters, skimmers, and pumps. You should also monitor your coral regularly for signs of stress or disease, such as changes in color or the appearance of lesions or other abnormalities.

In conclusion, Acanthophyllia donut corals are a beautiful addition to any reef tank, but they do require careful attention and care to thrive. By maintaining high water quality, providing the right lighting and water flow, and offering regular feedings of meaty foods, you can keep your coral healthy and happy for years to come. With regular maintenance and monitoring, your Acanthophyllia donut coral is sure to be a highlight of your reef tank for years to come.
