LPS Flesh .. Swollen/Saggy?

[ScubaFish802]

Ever since setting up a new tank and transferring coral over, my Duncan's have started getting 'swollen' or 'saggy' looking at the base of each head.

Is this any cause for concern? In the previous tank the flesh always looked 'tight' to the skeleton at the base

Looks like a happy healthy coral to me. I dont think there is anything to worry about, but will tag along here.
