The Parazoanthus spp., commonly known as the Bali Polyp, is a beautiful and vibrant colonial zoanthid species. This coral is known for its bright yellow to golden polyps with long, delicate tentacles that sway gently in the current, adding movement and color to any reef aquarium. These polyps typically grow in mats over rocks or other surfaces, and can spread quickly under the right conditions, making them ideal for creating a colorful carpet-like effect.
