What is this yellow network of strings?

Just showed up, and don't appear to be there 12 hrs later? I have a video as well, but struggling to share. Thoughts?

P.s. first post on the forum, sorry if I put in wrong place

Almost seems like the stomach of another coral trying to eat it. It's color is like a sponge though but I've never seen a sponge layout like that.. interested to see what that is.

Looks similar to a spaghetti worm

Mensenterial filaments.

It does but mine are really dark, are there spaghetti worms this color? I suppose there could be.. they have a really long defined body then all the noodles.. could it be eggs of some sort?

Looks like a spaghetti worm. Does it move around?

Wow, never seen this before. Good info

poriferan sponge.
While a spaghetti worm can have yellow strings- This would be excessive for one worm and they favor sand beds to get to detritus.
Take a dental pick or small crochet needle and pull the sponge away carefully.

I haven't witnessed it moving from place to place, but it's not on the duncan anymore. It's strands do bounce a bit with the flow of water and isn't statically sitting on the coral itself.
