Thanks Karin that definitely looks a lot more like what I have. Only problem is I am not sure if its bad or good. Some sources only talk about removal of it while other says
Neomeris Annulata is very reef safe and will grow well in a reef environment. It is unlikely that the Neomeris Annulata will become invasive due to its high mortality rate and its slow growth
Yet the same article even says
The best solution is manual removal since most fish won’t eat it, chemicals hold the potential to kill animals in your tank and Neomeris Annulata can survive drops in calcium, magnesium, nitrates, and phosphates. You will have to stay on top of it until it is gone.
So now I am unsure as to what to do with it. I like the looks of it but dont want it to go crazy on my rock work just make a nice grassy bottom. But I need to make a decision because I can see that it is adjusting well and looking like its getting ready to put down some holdfasts.
