Keep a watch on it, I think it might be a sponge but who knows...

Fairly new to the hobby, are either of those harmful for the coral? Thank you for the response!

Neither should be harmful. Most likely if it grows towards the Goniopora's tissue/polyps the Goni will hold its own. In most instances I've seen with coral warfare the Goni always wins.
