Frogspawn splitting? Swollen

[Picoflreefer.]

So my frogspawn I’ve had for about A month Has been one of my favorite corals to put into my tank. It Opened up the same day I places into my tank has been open every day since. I got it at the lfs as a 2 head. I’ve noticed another head in the middle forming the past week. Tonight when the lights went off I looked at the tank and noticed the frogspawn heads were all swollen. 3 heads now. There’s the pictures. What does this mean??? Normally isn’t all puffed up at night

Swelling at night isn't normal but could be just adjusting to your tank still. Looks like a healthy coral to me.
