This is a unique zoa with subtle colors and an interesting pattern that depends on the lighting. Under white lights, it has a yellow-green skirt and mouth with a blueish face. Under the blue lights, a fluorescent red ring appears on the face.
Like all zoanthids, these like plenty of nutrients, and will thrive in a wide variety of light and flow levels.
The frag you purchase will come from the same lineage as the image shown, and will have a similar number of polyps, but because of natural variation among frags yours may not look identical to this image.
