The most desired of this easy-care coral, the Colored and Metallic varieties of the Button Polyp Coral, Zooanthus sp., are richly hued and an excellent coral for aquarists of all skill levels. The Colored variety is typically green (pictured) while the metallic variety fluoresces vibrantly under actinic lighting. While Button Polyps grow in a matted cluster, they are not connected by a common base (as seen with Colony Polyps.) It will grow in many lighting conditions, but prefers medium to higher light levels for best growth and expansion results. Water flow level should be moderate, neither too strong nor too weak. This coral has a medium aggression level and does require placement where it has room to grow without making contact with other corals, to which it may cause harm. By placing “starts” at several locations, it can make a dramatic carpet effect over time. Though it produces its own natural nourishment in the wild, Button Polyps can benefit from occasional target feedings of plankton or brine shrimp, as well as foods designed for filter feeders such as Marine Snow or PhytoPlex. Calcium and strontium will help ensure its continued health.
Approximate Arrival Size for Button Polyps: Small - 2" to 3", Medium - 3" to 4.5", Large - 4.5" to 6"
