Ok so just had a photo from my friend she's cleaning up the tank and found this any ideas I was thinking either a type of anemone or maybe even a coral forming of some type best pic she could get

 

[Palyzoa]

Looks like a ball anemone, usually not a problem.

I'm seeing good and bad reports on these is it worth moving it on or keeping I had an anemone that had one of my fish so she's worried . I think at this size it's not a problem but obviously they grow lol
