Zoanthids are without a doubt some of the most popular soft corals for beginners and experts alike. Fast growing, super hardy, and available in every color of the rainbow, they are easy to keep and fun to collect. New and unusual color morphs are always being sought, but even the 'common' variants often possess stunning colors. Other soft polyps, such as Palythoas, Yellow Polyps, Xenia, and Star Polyps are all very similar in requirements to the Zoanthids and are equally hardy. These soft polyps are easy to frag. Most grow by encrusting mats or runners over the live rock to which they are attached. This can then be cut in between polyps, usually with little harm to parent or frag. Zoanthids and other polyps are easy to care for and are low to moderate in aggressiveness. Generally, not prone to stinging their neighbors, although they can grow so quickly that they overtake slower growing corals. Many do put chemicals into the water that can irritate other corals, so diligence in water changes and carbon use may be especially beneficial in a mixed reef that includes them.
They prefer low to moderate lighting, although many will do fine under stronger lighting if properly acclimated first. Moderate to intense water flow is recommended to prevent detritus from settling upon the polyps.
