This has a similar pattern as the other various Vampire varieties, but with a unique yellow and green color combination. The large polyps have a bright yellow outer ring, a dark inner ring, and a bright green mouth. This is a fast growing variety that maintains good colors in any light level.
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.
