Could someone please help me ID this little thing?

Found this after a water change today. Is it a baby majano?

How big is it? Looks like you have 2 of them in the picture.

Funnily enough, they are on a rock underneath a flourishing mushroom colony.

How can I tell the difference between ball/majano? Don't want to leave it only to get an infestation...

Probably the easiest way is that ball nems have little balls on the tips of the tentacles while majano tentacles are like regular anemones.
