Zoa Problems!!

[jessicagascoyne]

Ok guys, help me out. I am new to this so I don't know much.

These polyps were on my LR when I got and they were doing well. They have been in the tank for a week, but today I noticed these white dots on the underside. One of the polyps was starting to close as I was taking the picture. There is a mushroom at the top of them. Could it be harming them? Or is it Zoa pox?

Water parameters are all good, 78' F, 1.024-1.025 specific gravity, LED reef capable lighting.

They look fine.
The spots are probably sand.
Not to worry.

i have similar looking white dots on some of my zoas. they came in to my possession that way, and haven't had any issues growing and thriving.

presumably it's just sand like Grandis said, or something to do with their coloration that is naturally occurring.

as long as they're not "blisters" aka Zoa Pox, there shouldn't be any issues.

Button polyps use sand in their structure as the grow and spread.
