Button Polyp Rock - Protopalythoa sp. - Large

Button Polyps (Protopalythoa sp.) are an excellent choice for the reef tank beginner. They are found in various forms and colors. Typically, their polyps are brown or metallic green in coloration but some may also be red, pink, orange or combinations of colors. Some polyps will even have prominent "eyes" of white or green or may be striped or mottled on their surface. These are attractive in the aquarium due to their color and their encrusting nature.

Button Polyps are larger in individual polyp diameter than many other varieties. Many species can grow to around an inch in diameter while some of the larger, more rare species can grow to two inches across. Individual polyps have fringes around the rim and have been compared in appearance to the "teeth" around a Venus Flytrap plant.

Under the right conditions, these polyps may grow quickly and may be invasive to other corals. However, providing amble room between corals in the aquarium should prevent them from becoming too invasive. Invertebrate food such as MicroVert, Marine Snow, Cyclop-eeze or similar items are recommended on an occasional basis. These polyps are extremely hardy, low maintenance and adapt well to most lighting environments. However, the more light they receive, the more vibrant their coloration will be.

Button Polyps secrete a toxin known as "palytoxin". This substance is known as one of the most powerful and dangerous toxins in nature, but a reaction beyond a mild skin rash is very rare. Avoid coming into contact with Button Polyps for prolonged periods or with any open cuts or wounds; the use of gloves when handling your polyps is recommended.
