Help me ID this

My uncle and I found something in his reef tank that we can't seem to figure out what it is. The pictures aren't the greatest because the thing is small for the camera to zoom in without it looking blurry.

I’m curious to know what that is too. Don’t touch it

Ball Anemone (not an actual anemone; it’s a Corallimorph, so it’s related to soft mushroom corals). They’re not usually an issue, but sometimes they reproduce quick enough to be considered a pest.

Thanks for that info.
