Trachyphyllia all puffed up. Normal?

I just got this guy about a week ago and the past few days he's been all puffed up like this when the lights are on. At night he shrinks and looks like the trach photos I see on the web. Is this normal?

his fine probably eating something, btw nice looking corals.

mine has been doing that every so often since I got it like like seven or eight months ago and it appears to be perfectly healthy. I don't think you have anything to worry about.

Mine does it as well. It's nothing major. I believe that's how they move around when needed(Yes they can move. . . slowly but they can move) Kinda like a plate coral. It might feel crowded or in need of space. Try giving it a little more space. I know some people might have mixed reactions of it moving but mine does it here and there.
