Can you name this?

Wondering if anyone has a clue as to what this is. Guessing it hitchhiked on the Chaeto I purchased. It’s covering a large portion of fuge. Has not yet made its way to display- or what I can tell. TIA

Hydroids, this type is relatively harmless and they usually dissappear after awhile
