Dear marine aquarium enthusiasts, could you tell me what those thin white worms covering the rock are? They appeared suddenly and in large numbers. I don't know whether to be worried or not. I will add a photo.

Are they really planarians? They are so tiny and motionless.

I understood who you are talking about, I also have a billion of them, in the specific angle of the flashlight's light, microscopic fringes are visible, suggesting some kind of micro fan worm.
