A tiny....something?

[SallyWho]

I've got a handful of these small things hanging out on some rocks near the sand bed. They're about the size of a smaller zoa polyp. They don't quite look like majanos to me but google isn't always gospel. They're kind of pretty- I just want to make sure they're not also harmful. Thanks!

I believe those are ball anemones. Usually come in on live rock. You do hve many aiptasia too, in case you were not sure.

right on the nail with both ID's. OP, you have both ball anemone's, and aiptasia.

Thanks! Are ball anemones something I need to worry about? And yeah....that aiptasia sucks. The berghia I bought last fall appear to have died, so I recently got a dozen peppermint shrimp. They're slowly but surely whittling down the numbers!

they can still sting, so i would be weary of leaving them be next or around other corals.
