Another ID these please

[GregAW]

Well I'm seeing quite a few of these on some of my rocks. They are more of a grayish white in color.

Thanks in advance.

Do they move? Can you see a hole in them where they might be filtering water into?

 

[GregAW]

They don't move but they do have a hole in them. They look like semi flattened spider eggs. The only way I can really describe them. I don't see anything protruding from the holes.

 

[GregAW]

Took another photo and I hope this shows the holes you were talking about.

Sponges. They are beneficial and a sign of a maturing aquarium.

Oh good. Whew, I thought I had a plague going on in there.
