Was given these by a buddy that was tearing down a tank. His said, "I don't remember what these are but I think they're from wwc". A search has found nothing. They are TINNNYYYYY, like seriously small, these are all on a 3/4" frag plug.
Likely a WWC starfire zoa which is a rebrand/morph of the 'ring of fire' zoa.
I don't know them to be micro zoas, it could be they were getting a lot of light causing the smaller polyps/ slight variation in color. Once they're established and looking happy I might move them to a lower light area and hit them with some reefroids.
