Platygyra is a genus of large polyp stony coral (LPS) that is popular among reef aquarium hobbyists due to its interesting and unique appearance. These corals are relatively easy to care for, making them a great addition to a beginner's reef tank. However, proper care is still essential to ensure the coral thrives and grows in your aquarium. In this blog, we'll discuss some important tips on how to care for Platygyra in a reef tank.

Lighting:

Platygyra corals require moderate to high lighting conditions. They require a PAR (Photosynthetically Active Radiation) of around 150 to 250, which can be achieved by using LED lights or T5 fluorescent bulbs. Make sure to position the light at the right height and angle to avoid burning the coral.

Water Parameters:

Maintaining stable water parameters is critical for the health of Platygyra corals. They prefer a temperature range of 72 to 78 degrees Fahrenheit and a pH range of 8.1 to 8.4. It's also important to keep the salinity levels between 1.025 and 1.027 and maintain stable levels of calcium, alkalinity, and magnesium. Regular water changes are essential to keep the water parameters in check.

Water Flow:

Platygyra corals require moderate water flow to thrive. They prefer a gentle, random flow that is not too strong. A good rule of thumb is to have a water flow of 10 times the volume of your tank per hour. You can achieve this by using powerheads, wavemakers, or circulation pumps.

Feeding:

Platygyra corals are primarily photosynthetic, but they do require additional nutrients to thrive. You can feed them with a combination of meaty foods and supplements. They will benefit from occasional feedings of small pieces of shrimp, fish, or mysis shrimp. You can also add phytoplankton or coral foods to the water column to supplement their diet.

Placement:

Platygyra corals should be placed in the lower to mid-levels of your aquarium, where they can receive moderate to high light and water flow. They should also be placed in an area where they can expand and grow without being overshadowed by other corals. Be sure to leave enough space between the Platygyra and other corals to avoid aggressive interactions.

Disease and Pest Management:

Like all corals, Platygyra can be susceptible to diseases and pests. Regular observation and maintenance are crucial to preventing and managing issues. Keep an eye out for signs of tissue recession, discolored patches, or pests like flatworms or red bugs. If you notice any issues, take immediate action, such as removing the affected coral or using appropriate medications to treat the problem.

In conclusion, Platygyra corals are a beautiful addition to a reef tank and relatively easy to care for. By following these tips and maintaining stable water parameters, lighting, water flow, and feeding, you can help ensure that your Platygyra thrives and grows in your aquarium for years to come.
