Zoanthids, Zoanthus sp., also known as Colony Rock, Zoas, or simply "Zoos", are an extremely hardy and excellent beginner coral. They are small soft corals that vary greatly in color and pattern. They have the ability to spread rapidly about the tank so be sure to keep extra room between them and other corals.Zoanthids thrive best in tanks with low to moderate waterflow and strong lighting. They will largely feed photosynthetically but will benefit from supplemental feedings of plankton and other carnivorous foods. Zoanthids are some of the most popular, hardy, easy to care for, and beautiful corals in the entire trade.
Love these zoas but my wife won’t let me get more because I already own so many. You get a good size frag with lots of polyps for a fraction of the price you would get anywhere else.
