Updated pic, @thrillreefer Beautiful (I explored the lighting vs morph relationship, this one has stars and swirl pattern), slow grower (especially if you only have one poly), easy to melt (even my strain is hardy, I have melt several). You can also do some search.
This is stratosphere. Exosphere and stratosphere zoas look really different, even in color (green vs purple/pink). BTW I also have exosphere zoa for sale (I will update my previous post with latest pics tomorrow).
