Hello, I was looking at my Duncan coral, and I noticed there’s a yellow spot on it. I tried searching it on Google to find out what it was, and I don’t know if it’s some kind of worm, or it’s due to water quality or water flow.

Here’s a picture under white light. It has multiple yellow spots. Is this what new heads look like?

Could be yellow sponge growth, does it move or come off easily?

I think that might be their natural color, my Duncan has that color on their stems, see pic.
