This is a red variant of the classic Orange Oxides. Its the same pattern, but in a bright, true red. These very small polyps feature a bright red face with a dark outer ring and a dark mouth, and a bright red skirt.
Like all zoanthids, these like plenty of nutrients, and will thrive in a wide variety of light and flow levels. This one holds its colors under any light levels but really prefers low light.
The frag you purchase will come from the same lineage as the image shown, and will have at least 3-5 polyps, but because of natural variation among frags yours may not look identical to this image.
