What this on my GSP?

Coral is doing fine, but noticed these white “vines” growing on the bottom. Any thoughts on what it may be?

Sponges

So ok to leave them be?

Mother nature will take care. :)
Most of the time, stuff we find are harmless and a good sign.

That’s what I figured, but Mother Nature killed half of my fish, and the other half are in a treatment tank for about another month. I just don’t want to get overrun with something while I wait to get my fish back in the display.

Especially because I’ve noticed some bubble algae coming back now that my Foxface is being QT’d.

Sponges are good.
