Scaredone

Started out with about 2 of these when i started the tank didn't think much of them thought they were some sort of polyp, now they've grown to be about 2cm in diameter and are up to 5 that i can see. Doesn't really look like any aiptasia that Ive seen in pictures hoping the pros would know. If it is Aiptasia what would be the best way to deal with it?

It looks more like a Palythoa coral to me, but I can't rule out that its not aiptasia. Its coloration looks like aiptasia. I've had success with Aiptasia X.

cerianthus

I agree with either paly/zoa. I havnt seen Aipasia with such short and many tentacles.
