Common name: Zoanthus pacificus

General information

Zoanthus pacificus, commonly known as Pacific Sea Mat or Button Polyps, is a species of colonial zoanthid that is popular among reef aquarium enthusiasts. These polyps are known for their vibrant colors and the ease with which they can be kept, making them a favorite for both beginners and advanced hobbyists. Each polyp is a distinct individual, but they are connected by a mat-like coenenchyme, giving the appearance of a single large organism.

Care

Pacific Sea Mat is relatively easy to care for in a reef aquarium. They require moderate to high lighting and moderate water flow to thrive. It's important to provide them with a stable environment and maintain water quality, as they can be sensitive to fluctuations in water parameters. They can feed on microplankton and will also benefit from targeted feeding of fine particulate foods.

Symbiosis

While Zoanthus pacificus does not have any specific symbiotic relationships akin to clownfish and anemones, they are often found in close proximity to other reef organisms. They can coexist with a variety of other corals and invertebrates, provided they have enough space to grow without being overgrown or shaded by their neighbors.

Habitat

Pacific Sea Mat is found in the warm waters of the Pacific Ocean, where it inhabits reef slopes and lagoons. They often settle on rock or rubble substrates and can be found at various depths, typically where light is sufficient for their photosynthetic symbionts, zooxanthellae, to thrive.
