Anemone ID - unusual

[OrionN]

Hell’s fire anemones are from the genus Actinodendron.

Heterodactyla hembrichii is not a Hell’s fire anemone. Only the verrucae sting. I can see the verrucae quite clearly on some of the pictures in the first post.

Like most common name, Hell’s Fire anemone is imprecise. I think several anemones are called Hell’s fire. H. hembrichii have the berry tentacles which this anemone does not have. And the OP stated that there are no prominent verrucae

A better picture of the mystery anemone, it appears to like the sand which is maybe a clue.

I re looked at it, it does have verrucae, sorry, they’re very similar to the body colour so was hard to spot.

@OrionN so you think the malu’s tentacles will get longer?

Yes

I do see the berry tentacles so it is likely a H. hembrichiii
