White hairlike growth.

[Galeno rocha]

I have these growing in my rock work.
It appears to have originated from the clove polyp frag and is slowly spreading to the rockwork.
It feels both brittle and hairlike to the touch.

I dont't see tentacles of any movement.

Any idea what theese are?

If I’m seeing the picture correctly and understand you to say that it originated from the clove/wood polyp, then you’ll be seeing a whole lot more of this as the wood polyp spreads. As I’m sure you’re already aware this coral spreads quickly. Down the road when you remove some of this coral from your rock you’ll see how the brittle hair like stuff pulls off with the coral.

It is possibly spagetti worms

The hairlike growth seem to be preventig the coral from spreading. The polyps have quadrupled in size in about one and a half years, but haven't grown beyond its boundaries.

I have something that looks like spaghetti worms in the sandbed, that matches the ones depicted in the sticky thread and look very different from this stuff.

Could it be a different species?
