Ricordea acting very strange

[Pablopufferfish]

Hello, my Ricordea has been acting strange recently and it now looks like this:

Can someone tell me what’s happening? I’m very worried.

Whats your water parameters and what testing kits/devices?

What equipment do you use? Lighting?

I reposted this in the soft coral form.

That was a picture from this morning, right now it’s splitting. I got worried this morning because it had done this overnight and looked like it was doing something worrying , but it’s splitting. Nothing to worry about. Anyhow my parameters are perfect and my lighting is just fine with the tank size. I use API testing kit and a refractometer for salinity.
