Favia Help

[Charles Weller]

Can anyone ID this growth on the base of my Favia?

It's blurred but it looks like a harmless sponge.

Thank you. That's what I thought, but figured it was better to be safe. Didn't want to glue it in place and find out it was something else.

I would also guess sponge; hopefully a helpful filter feeder at no extra cost.

Definitely looks like a sponge. I have some on my LPS corals. It's a little blurry but kind of looks like it. Shouldn't be an issue.
