Anyone have any idea what these are?
I got them from a wild rock of zoas about a year ago. They were originally solid baby blue. I have them in a tank that has lower light (2x65W PC over a 29G). They faded out to a pale greyish color and I sort of just left them be for the longest while. A few months ago I moved and changed the tank. These ended up on a rock about 2/3 the way up the tank. Over the last few months they're regained their baby blue coloring and have just the faintest bit of green on the tips of the skirts.
