Pooping zoas?

[Papadovak]

My zoas had been looking bad for quite awhile so I decided to dip them in melafix. Found some "bugs". They are looking better but now it looks like they are....pooping any ideas why?
Before the dip.

About a week after the dip.

Sorry for the shotty pics I took them on my phone.

What they filter out of the water eventually has to leave the polyp. The mouth of the polyp is the entrance and exit.

Everything poops No worries, if that's on a frag plug, you might want to move it up, IME, the stalks grow long when they want more light.
