Blue feather inside GSP

[BlakeB58]

I recently added this small GSP frag to the tank and within a couple of days this blue feather started popping up like crazy in it. Any idea what it may be? Do I need to remove it or scrub with a toothbrush potentially?

Any chance you could get better pics? Doesn't look like anything harmful, looks pretty cool. @ISpeakForTheSeas any ideas?

Not sure what that is.

But, your GSP is very bleached. Is this your first coral?

Oh yeah it is, I didn't notice that before. What light are you keeping this in?

Yes it is.

Light is the factory light on the Biocube 16.

The most likely is a feather caulerpa or bryopsis species that looks blue due to lightning:

Yeah, I can't see the offshoots from the stems well enough, but it's either Caulerpa or Bryopsis.

If it's Caulerpa, it'll have a stolon (a long "root" that runs along the surface of the substrate connecting each "feather" together at the base); if it's Bryopsis it won't (Bryopsis has rhizoids, which look more like actual plant roots).

Other options are substantially less likely, and I would need closer pics to say for sure if it's any of them.

How close to the light is it? How long ago did you get it?
