They look like hydroids to me. It's possible they could be aiptasia but the tentacles appear to be extremely thin. The photos are rather blurry to be sure.

looks like hydroids

if they are dont panic , its common in new tanks and it should go away with time .

Hydroids will have a visible tube that the tentacles come out of. These tubes will still be visible when the tentacles retract. If the entire animal retracts when you disturb it then it's likely Aiptasia. I still can't say for sure from the pics.
