Can some identify this ?... Bathycrinidae ??

This came in on a plug about 5 months back, but I thought it was just some simple algae growth when it was small and started to show up...

I kept trying to get rid of it over time, by plucking, dipping in peroxide, isolating in separate frag tank, etc...

So I finally just let it grow...looks like palm leaves on separate stems and is green with a blue tint.
The coral never grew with this on it either, still the same as when I bought it

Looks like Caulerpa algae.

Looks like Bryopsis to me.

If it is Bryopsis, you'll eventually want to take a look at this thread.

I just looked Bryopsis up and it can have a blue hue to it, that would explain the manual removal not working, since it is rooted and entwined in the coral frag itself. (I removed it from the plug when I received it)

Thanks guys !

@Tft12, I believe your correct. I just glanced at the Op’s picture.

Unfortunately, I've pretty much always got a little tuft of Bryopsis to look at somewhere. I'll be needing another round of flucon in a few weeks/months.
