Is this an SPS question or critter question

Hi everyone,

I got this mariculture piece Saturday and Bayer dipped it before putting it in my tank. Today I noticed this weird pulsing motion occurring on the frag. It has good PE and seems happy, but I just can’t figure out what this is!

May be a barnacle. They often are incorporated in to the skeletons of stony coral.

As long as it’s nothing bad, that was my only concern

That is a new one for me, sorry no idea

Yup to barnacle and harmless.

Thanks! Have never seen a barnacle encrusted by a coral before.

I would go barnacle as well.
