Looks like a little cup coral to me, but I've been wrong before

Maybe a little rock anemone?

Doesn't look like aptasia, so I wouldn't worry about it.

It retracts it's polyps during the night... And I have lots of them...

 

[Paintbug]

when it retracts do you see a skeleton? if you do its a cup coral. if not its probably an anomone of some kind. if you have lots, its probably a pest on top of that.

Nope it looks like an anemone when comparing body characteristics. When I say lots, I counted about 6-7 in a 550l tank with 80kg LR
