Aiptasia???

[DaGoose]

These little guys showed up about a week ago...

Not sure exactly what they are and if I should be worried or not.

Any advice or help is greatly appreciated.

They look like aiptasia, possibly manjano

They are pests and can spread very quickly

So it needs to go, correct?

Lemon juice syringe operation?

I would be careful with injecting them. I'm not against it but the chances of it failing can be high and you risk them spreading. Can you remove the rock? I like taking out the rock when possible and glue them. And there are inverts like peppermint shrimp that eat smaller ones. Chances are that you have many more maybe to small to see right now.

could be...all the glass anemone that I have experienced, had a less defined tentacle....

Phyllangia americana, the hidden cup coral. I had one hitchhike and of all my corals it’s still my absolute favorite.
