GSP sponge?

[GazS]

Hi all,

This morning with the lights off i was doing a water change and noticed this on my Green Star Polyp, it seems to be only visible in the morning when the GSP is retracted, kast night it was open and healthy, not sure if later it will open up and hide this again.

Any ideas on what this is? Im thinking a sponge? treatment needed?

Thanks for any help!

It’s a sponge, nothing to worry about, the GSP will grow around it.
