This is a classic variety that for some reason isn’t widely available anymore. Large polyps with a bright red face, a dark skirt, and a blue center. Pictures don’t do this shade of red justice – it is a true bright red with subtle streaks of orange radiating from the mouth.
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.
