That is my one remaining zoa colony. I've decided that I'm not overly fond of zoas, though I do really like these ones. I received it from sphelps.
There are a few of the polyps with the pink spatter on them. There are three different morphs at I can see. If the frag rack the urchin is on wasn't so desperately in need of cleaning I'd pull out the DLSR for a better shot.
Now, what I'm wondering . . . Do I let the urchin truck around with them for a while? He seems to hold onto things for a week or two. The zoas look good for now. Maybe if they start to look stressed I'll try to remove them?
