Help me ID these blobs growing around my tank!

[DowntownJosh]

See pictures of light green/yellowish blobs with tubes sticking out of them. So as with many things, these started as just a few, and are now everywhere in the tank. I have no idea what they are, if they are bad, and how to get rid of them. I tried googling, and everything that comes up is bubble algae, which this is not.

Thanks!!

They look like some sort of sponge to me... I'm not an expert but I would say it might show that your tank is healthy!

Agreed! Some Yellow sponges. They won’t take over. And I’ve never heard of any major problems.

Oh, that's a relief, they have been growing like crazy on the underside of my rocks. Good to know they aren't harmful. Guess I will just let them be. Thanks for the info!

I think the specific term is 'cryptic sponge' for those which grow under rocks or in shade. I'm pretty sure it's a sign of a healthy tank.

No problem. Keep in mind that some sponges if disturbed can release toxins. Not sure if they’re one of them? But yes just let them be. You should be fine. I have some blue ones in my frag tank with my sps. I just leave them be.
