White strands appearing all over rocks

[Garcia2460]

Hello,

I have recently started noticing a bunch of these white strand like strings stretching from my rock work. Wondering if these are things I should be worried about. And if so, how I can get rid of them.

I tried getting a better picture but this is the best I can get at the moment.
Thank you

Possibly bryopsis. Not good if it takes over.

Digitate hydroids.

do I need to be concerned about these?Or can I leave them be?

You should remove them. If you can, dip the rock in coral dip or something

Candelabrum sp hydroids.

I’ve had them for years, no luck attempting to remove them completely.

Have you noticed them interrupting anything? Or damaging corals?

Not damaging as far as I could tell, but anytime I’d find one near a coral that seemed irritated I’d just move the coral.
