Sunny D, the zoa that shows a rainbow of bright colors but somehow got named after an artificial orange drink. This deserves a better name, with yellows, reds, and greens that show up under white light and absolutely glow under blues. Big, colorful polyps you can see from across the room.
Like all zoanthids, these like plenty of nutrients, and do well 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.
