Frogspawn not opening but hammer and torch are ok

[skyrye7]

I have a frogspawn for a month now. When I introduced it to the tank, the frogspawn is opened up and happy. I have never moved its position since then.

But a couple of days ago, it is closing up. My hammer and torch are happy and have not been impacted.

Alk is 7
Calcium is 430
Mag 1350

I really don't know what happened...anyone can help? I am ruling out flow because I have never changed the frogspawn's position

Your alk is a little low compared to your cal, they're not in balance. You have a lot of green stuff growing. Do you have anything to check your phosphates accurately?

Is it possible it got stung or bumped? Looks like it has brown jelly and is fully infected. Unfortunately it doesn't look like it will recover :/

Don't give up! I had a branching hammer that was a single polyp. Yes - one polyp amidst a white skeleton. Here is a picture of it from a few months ago. It's bigger than this now and splitting again!
