Strange apraxia variant/ID?

[Perpetual Novice]

I’m servicing a clients tank and they have these small aphasia looking things everywhere with an unusual (pretty?) coloration. They seem resistant to aptasia x. Historical pearlscale butterflies will eat them I’m told. Anyone know what these are?

I almost want to say that they are yellow parazoanthus, but the tentacles look a little too stocky.

Majano?

Majano?

They certainly have that shape.

Looks like a species in the Anemonia genus
