Maze brain coral question

[Kaykay101]

Hi all! I got a maze brain coral recently and I've noticed that it's feeder tentacles are bubbly looking, is this normal or a cause for concern? And if it is what could cause this and is there anything I can do about it?

My first reaction was a coral that is puffing up is healthier then one that is suckin or sucked in. But I’m wondering if that coral has made contact with its neighbors and may be in a state of defense.
