A sponge of some sort?

Brand new member here, and hoping someone can confirm for me...

Thanks in advance!

Are you reffering to the white stringy looking things?
If so appears to be a String type sponge.
Harmless, i have this in my setup as well. Just be forwarned this stuff grows like crazy.
I take my rock out once every 3 months and scrub this stuff off.

 

Yep! That's exactly what I was referring to!
Thanks for the confirmation! And I'll keep its growth in mind as well!

 

Hi,

I think that I have the same thing that you do. I asked about it this week and was told it was a sponge and that they are filter feeders. Good to have around. I found this site that has a picture of what I have (Scypha sponge):

It's definitely not a scypha sponge AKA pineapple sponge.

 

Looks like Halichondria bowerbanki or a similar species. Key IDs for this species; tassel growth and cream colour.

I missed that. I was looking at the right side of the picture. Good eye!!!
