Should I cry or is my hammer ok?

[Bradsreeftank21]

So my massive hammer coral looks a little diffrent tonight. He was very happy today and actaully ever since I bought him he’s been happy. I just noticed tonight’s as he goes to sleep he looks very bubbly. Is this normal?

I doubt anyone can see anything but blue.
You’ll get good answers with corals under natural white.

They can retract at times. Normal.

Have you done anything different lately? Dosing?

What are your parameters?

Any swings lately?
