Worm? Tissue? Help me identify please

There is some type of branch like tissues on the underside of my blasto frag. They are not hard and don’t appear to move when I touch them. They are transparent in color

Looks like some kind of sponge, but they usually die when they're exposed to air so you probably don't have to worry about it any longer. What does it look like in the tank?

Most likely some kind of sponge, do you see a valve?

Awfully hard to tell with frag out of water. Please add a couple of pics under white lighting
