My zoas have spots?

[lmfbs]

I bought these zoas from another reefer's tank 6 days ago. Yesterday their stems seemed a bit swollen and whitish, but the swelling couldn't be blown or rubbed off, so I assume not a fungus. You can see some of it in the pictures. The polyps were opening fine. The light isn't on yet today so they're not awake.

Today the heads have some white spots. Any idea whether this is an issue/how it can be treated?

The tank is new (3 weeks>, cycled with a small amount of established rock and mostly dry rock with bottled bac. I have some other zoas which are totally fine.

Ammonia - 0

Could just be dust or rock chips from that dry rock or even sand does it blow off easily?

I don't think so, they look embedded. You can see the white...coating? On the stem now they're opening up a bit

Are you talking about the white spots by the tips of the head?

Yup! And separately, the whitish gel like coating on the stem

Up at the tip of the head is just the polyps poking from the inside would be my guess
