Identify velvety growth on corals

[thecodingart]

Would anyone be able to help identify what this thing is?

It’s velvety with a slight prick around it. Has a hollow portion on the inside (as shown in the pictures).

It’s almost egg sack like and is very squishy. Was growing on the side of one of my polyps.

Looks like its just a sponge.

Hu, it just came out of nowhere.

So basically not harmful or meaningful. I have no idea what this guy hitch hiked on.

Be careful with them growing right next to coral bases or branches. A few types will snuff out and kill the corals close by over time.

Yeah, I plucked this guy out because I noticed that and have no intention of reintroducing it.
