What is it?? Friend or foe

I just noticed this white stuff on one of my zoa frags. Anyone have any ideas?

Any chance of a clearer picture with some whites on? My first guess would be sponge of some sort.

Sponges, if it starts covering the zoas just scrape it off...
Other than that, they’re just part of a normal tank

I will try another picture. I hope it’s only a sponge

Is this better? I only have an iPhone

It's sponge, harmless but can grow over corals. I would remove some from the zoas

Sponge, as others have said keep an eye on it if it starts to overtake your zoas you can just scrape it away
