Odd like string worm killing corals

[Big_Als_London]

Good day fine folks here on the fragtank. I am posting for a customer as I have never seen anything like this. 200 gallon aquarium and my customer is starting to lose some mushroom and I think possibly these little work like creatures are doing the killing. I've never seen these before in their aquarium. I've read about spaghetti worms, but they aren't really a killer and mostly live in the sand bed. He hasn't added anything new to the tank in a few months. Tested everything and other than 20ppm nitrate all is fine. What say you? Has anyone seen this before?

Odd... are those structures rigid or flexible? They look like fungal growth patterns but there are no "nodules" and some of it is in full light. I assume the customer has never seen snot or feathers coming from them?

I had a huge mass of something that looked similar albeit far denser in the back corner of the 60g when I took it down, never bothered anything and I never tried to ID it, just assumed tube worms.

Following along.

They are soft and move around.

I believe they are spionid worms

I'm not sure, I didn't see any hard tubes

I think what he meant by move around is swaying with the flow

Spaghetti worms, big enough populations and they can bother corals enough to kill them eventually, trust been there, living it...

If it is spaghetti worms it would be clear as day imo

They were not swaying with the flow. I have a grainy video of them and it's not flow related. If I can figure out how to post the video I will

Still going with spaghetti sponge or possibly spaghetti worm if they are independently moving. There seems to be several different sponges on that rock as well which is why I thought sponge.

Any follow-up to this?

Not really. We put in a 6 line wrasse and a sand sifting starfish. We will see in a couple weeks.
