hair algae? or something else?

[sheepersheep]

this is in my neighbors fish tank, it’s over about 99% of the rocks and i don’t know if it’s a white looking hair algae?
i don’t think it could be something like a hydroid, it doesn’t really have that feathered look, and comparing it to the hydroids in my own tank, they don’t look the same.

sorry if the pictures are bad, im taking care of the tank while he’s on vacation and the lights are controlled with an app.

This may be turf algae but these pics are too dark with blue lighting to tell or confirm. Please repost using bright white light intensity only

the lighting is controlled via app and my neighbor is on vacation, so i can’t change the light. but i’ll look into turf algae, see if it matches
