Maybe a feather duster??? What is this??

Saw this in my 90g saltwater reef that was given to be by a friend. Never noticed it before. The tank is 8ish years old has been in my possession for about 6months.

Sorry picture kinda sucks, he in the back of the tank under the rocks.

Looks like aiptashia.

Looks like aiptasia, definitely not a featherduster.

Should I get rid of it? Or is it harmless?
