My pink star polyps are on the left and the green star polyps are on the right with the 'eggs' in it.
I found other pictures online today that showed the same thing at it was the GSP spawning.
When I first noticed this I figured it was zoanthids spawning so I shut my equipment off to give them a chance to attach to the rocks. When I found out it was spawning GSP I quickly turned everything on to catch as many as I can
If it was my pink stars I would try and save them but I dont want to get over whelmed with GSP
