Zoanthid Corals: A Beginner's Guide to Understanding and Caring for these Colorful Invertebrates

Zoanthid corals are a group of invertebrates that are popular among aquarium hobbyists for their vibrant colors and ease of care. They are commonly referred to as “zoas” in the hobby, and they come in a wide variety of colors and patterns, making them a popular choice for aquarists looking to add some color and diversity to their reef tanks. In this article, we will discuss what zoanthids are, their natural habitat, and how to care for them in an aquarium setting.

What are Zoanthids?

Zoanthids are a type of soft coral that belongs to the family Zoanthidae. They are also known as button polyps, sea mats, or colonial anemones. They are typically small, with a diameter of 1-2 cm, and are found in a wide range of colors and patterns, including green, red, purple, yellow, and blue. Zoanthids are often mistaken for their close relative, the Palythoa coral, which is similar in appearance and care requirements.

Where do Zoanthids Come From?

Zoanthids are found in the wild in tropical and subtropical waters around the world, including the Caribbean, the Indo-Pacific, and the Red Sea. They are commonly found on rocky substrates, including coral reefs and rubble fields, where they form large colonies.

Caring for Zoanthids in an Aquarium

Zoanthids are relatively easy to care for and are a great choice for beginner aquarists. They do well in a reef aquarium with stable water parameters, good water flow, and moderate to high lighting. In general, zoanthids prefer moderate water flow and lighting, so it is important to avoid placing them in areas of the tank with too much or too little of either.

Water Parameters

Maintaining stable water parameters is essential for the health and well-being of zoanthids. They prefer a water temperature range of 75-80°F (24-27°C) and a pH range of 8.1-8.4. Salinity should be kept at a specific gravity of 1.025, and ammonia, nitrite, and nitrate levels should be kept as close to zero as possible.


Zoanthids require moderate to high lighting to thrive, and LED lights are a popular choice among aquarists for providing the right amount of light. It is important to acclimate zoanthids to any new lighting, as they can be sensitive to sudden changes in light intensity.


Zoanthids do not require feeding as they derive the majority of their nutrition from photosynthesis, but they can benefit from occasional feedings of zooplankton or phytoplankton.


Zoanthids are relatively easy to propagate, and many aquarists enjoy the challenge of growing their own colonies. This can be done by cutting a healthy polyp from a mature colony and attaching it to a suitable substrate. It is important to maintain stable water parameters and avoid overfeeding during the propagation process to ensure the best chances of success.


Zoanthid corals are a great choice for aquarium hobbyists looking to add some color and diversity to their reef tanks. They are easy to care for, and their vibrant colors and unique patterns make them a popular choice among aquarists. With proper care and attention to water parameters and lighting, zoanthids can thrive in an aquarium setting, providing beauty and interest to any reef tank
