something white on my star polyps?

[Angelajean]

Hello,
Can someone please help me identify the white stuff on my star polyps? And do I need to do anything?

Thanks, Angie

Looks like you got a sponge growing. They will come and go. Dont worry about the GSP. they will spread and be a pain later.

You can also pick it off the GSP if you dont like it
