This variety has tiny polyps with a bright green ring around a dark center and a dark skirt. These resemble Yellow Submarines except smaller and in green instead of yellow.
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, but because of natural variation among frags yours may not look identical to this image. This variety typically has 3-5 polyps per frag.
