Common name: White cluster anemone

General information

Parazoanthus anguicomus, commonly known as Yellow Polyps or Yellow Colonial Polyps, is a species of zoanthid that is popular among reef aquarium hobbyists for its bright yellow coloration and ease of care. These polyps are colonial organisms, meaning they form groups of individual polyps connected by a mat of tissue called coenenchyme. They are often found in a variety of reef environments and can add a vibrant splash of color to any reef tank.

Care

Yellow Polyps are relatively undemanding and can thrive in a range of lighting conditions, from moderate to high. They do well with regular feedings of microplankton or other suitable coral foods. Water flow should be moderate to allow the polyps to sway gently, which is not only aesthetically pleasing but also helps them capture food particles from the water column.

Reproduction

In the aquarium, Parazoanthus anguicomus can reproduce asexually through budding, where new polyps form directly from the base or sides of existing ones. This can lead to rapid colony expansion under optimal conditions. Sexual reproduction is less common in captivity but can occur, with larvae being released into the water column.

Symbiosis

While not hosting fish or other large symbionts, Yellow Polyps may have symbiotic relationships with microscopic organisms such as zooxanthellae, which are photosynthetic algae that live within their tissues. These algae provide the polyps with some of the nutrients they need through photosynthesis, while the polyps offer the algae a protected environment and access to light.

Habitat

Parazoanthus anguicomus is typically found in the Caribbean and adjacent regions. They inhabit various reef structures, often settling on rock or rubble where they can receive ample light and water flow. In the wild, they are usually found at depths where light is sufficient for their zooxanthellae to photosynthesize effectively.
