is this Zoa or anemone ID?

[czynot]

I purchased some live rocks from a tear down. The rocks are sitting in a bin and I see these polyp on it. First i thought they look like zoa but they they move and follow the light. I know one rock dont have any of them on it and over night one pop up on the top because i have the light on it over night.

They have green short stubby tentacles. few are brown. so far i can see 20 or so spread out over 70lb of live rocks.

Looks like Majano Anemones to me.

Get rid of them or leave them? are they harmless?

Majano spread like weeds and are considered a nuisance anemone like aiptasia. Get rid of them.

Get rid of them ASAP before they spread.
