This is a bright zoanthid with an interesting pattern. These medium polyps feature a dark face with a bright yellow mouth, with irregular streaks of orange radiating across the face. It’s encircled by a long, bright yellow-green skirt.
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, with about 3-5 polyps, but because of natural variation among frags yours may not look identical to this image.
