green star help coral reef new grow

Just received this GSP from a family friend. I can see up very close some of the neon green on the piece. How long would you expect until this grows out tentacles?

Hey, So I was out of the office for a few days, one of my green star polyps fell off the rocks into the gravel and closed up and hasn't opened for over 24 hours, Is there anything that can be done to help it? Or any assistance for this would be amazing! Thanks in advance Also if anyone...

So I have a green star polyp and I can’t tell if this is normal? Or if it got damaged it looks super healthy and I have had it for almost a year if anyone has input that would be awesome. It seems like the circled area is longer and or like puffy looking.

hey y’all i got a weird green star polyp i got it about a month ago didn’t reallt have a good place for it so kept it in my sand bed didn’t open up at all tried rocks but hermits kept making it off so i got another rock drilled some holes put it in now i tested the water every thing is decent...
