Hopefully there's someone here that can tell
Me what is this growing in my rock and what to do with it. Thank you

If your asking about the clearish looking (aptaisa) thing by the flame angel

 

[Mandarin15]

Oh it's aptasia? I was searching online Thought it was some kind of sponge.
There's also some yellow stuff on that rock.
So should I remove the whole rock?

 

[Coastie Reefer]

Pretty sure that's all sponge... I don't see any aptasia

 

[Mandarin15]

I'll take a better picture later thank you all
For the responses hopefully it's nothing serious.

Here are closer pictures these are only growing on this rock. Is this bad aptasia or
Sponge do I need to remove this rock? Please help thank you.

Definitely sponges. Good filter feeders.
