GSP not opening

[timbler]

Hey guys I’ve been able to grow gsps pretty successfully in my old setup. But recently I’ve been having trouble with this new tank I have. They seem not to open at all. My old gsp from my old setup (15G fluval flex) melted away in my new setup. Funny thing is that all my other corals are doing fines. Zoas, montis, hammer, acan, favia are doing fine in the new setup. I’ve left it in high light, low light, medium light and still closed. Also happing with my firework clove polyps. What could be wrong?

Ph: 8.0

How long ago did you move it? What were the previous parameters? Any light or flow changes?

About 3 months ago. The original gsp sadly melted away. But i bought a new one and its going through the same thing. Dont remember the parameters of the last tank
