Is this a rock flower anemone?

[Levinson]

Rock flower anemones are hard to find where I live (South Korea). I have seen them being sold in the past, but they are difficult to come by.
I came across this anemone being sold, but couldn't tell what it is.
Do you know if this is a rock flower anemone?

Looks like a shroom to me

Yeah, it looks more like a mushroom

These are juvenile RFAs (not my photo)

It could be a maxi mini anemone, FWIW

We need a better pic.
I am not 100% sure yet... Currently agreeing with shroom. But it seems it could maybe somewhere look like some sort of Phymanthus. In doubt.
