Is this white spot?

This is one I focus on a live rock

There are 3 on the glass

This is the whole tank view, I have 3 corals,two fish,2 blue hermits, 1 turbo, 1 astra, 2 nassaixxx snail.

Post those over in the invert forum, GT3: we have some small-life experts over there. I've never seen any quite like them, and I've been at this a while. Appear to have structure, like a small nem, but not aiptasia as best I can discern. Let us know what you find out. I don't think they're harmful: more a curiosity.
side topic: looks like you're getting a tiny bit of cyano, if I read that red stuff accurately. You might try turning your lights out 3 days once a month and see if your skimmer can pick up the resulting cyano dieoff. Or check the age of your lights: 6-8 months expires mh---dunno on the other varieties.

I have them too. They're a type of anemone in the aptaisia family. I kill them with aptaisia X.

Where is the invert forum, is it a section in reef central?

Do corals grow out of these eventually?

You are right, I also spotted little red slime stuff on my send and some rocks. Very likely cyano.

Probably not. Personally, if I get a new invert in live rock, I like to find out what it is, in case it's not common, in case it's a neat new species, etc. Do they crawl off or just vanish in light?

And the invert forum is http://www.reefcentral.com/forums/forumdisplay.php?f=427
"Other Invertebrates".

They would close their 'mouth' like my polyps, and open during the day. I found only one at the beginning of my startup, now I have around 7-10. Still not sure what they are but they do seem to grow larger slowly.

did you ever find out what that was
