Is this pinched mantle?

[Thizz]

My new ultra Ora maxima looks like it has pm.
Water conditions are stable and lighting is 6x24w ati
Is this pinched mantle?im really confused because these clams
Came from Ora,no other clams in the tank either.just the two I got from Ora.
Bubbles on frag rack are from
Skimmer in the tank not algae.

It looks like it maybe pinched mantle to me.

Could Ora really send the lfs one with pinched mantle?

 

[SeahorseKeeper]

It probably wouldn't be intentional, but can happen.

How did you light acclimate the clam? How is the clam now?

Do you run carbon?
