Unidentified Fuzzy Object

[JDRing82]

Hey guys! I have a biocube that is almost a year old. All parameters are good and fish and cuc are all healthy. Recently I noticed a small brown fuzz in one of the holes of my live rock. It has since grown and during a water change today I gave it a tug but that did nothing. Any idea what this could be? It’s hard to see in the picture but looks just like a wooly worm sleeping in there. Haha

White lights. Without being able to actually see anything in your pic, maybe pineapple sponge?

Do you have any turbo or trochus snails or urchins? If so, put one on the spot and see if they eat it... Really need a pic under whites, but it could just be a clump of algae.
