Live rock hitch hiker that I thought was dead, but in the last week or two I noticed it coloring up and it is re-encrusting areas that did die off. Growing over the rock at a rate of about a millimeter every 2-3 days. Anyone know what it is? It doesn't seem to like a lot of light. There is another patch that has an area that is more exposed to light and it is bleached in that area.
It doesn't really show in the photos, but the polyps are green and maybe 0.5 to 1 mm in size.
