What's growing around my mushroom?

Hi Team,

Was just having a look around the tank and noticed that my mushroom was lifting up and saw some something that looks clear growing and surrounding one of the pups. Also noticed some tentacles circled in red further to the right. Any clue what it could be? Thanks in advance!

I have those everywhere. They look like a sort of mycelium web, correct? Harmless filter feeders, I think they’re a sponge if not a tunicate

Interesting, I'll keep observing but mycelium web sounds right. Will see if it keep growing or not. Thanks for your response

They tend do grow mostly in shaded spots. I noticed population booms when I feed frozen and small particulate food
