Wierd reddish thing in my Goni frag (worm?)

[Pbh-reef]

This has been in my Goni frag since I got it last August. Noticed it changing shape recently - what on earth is it?

The least colorful photo is from this morning during lights off. The more colorful are from two nights ago while I spot fed the corals eggs. It looked kinda feathery that night. This morning it looked kinda long

I was going to say feather duster until i saw the last pic...now it looks more like cyano.... idk.

I really doubt cyano - it is always there, it changes shape and color, sometimes it looks like a black pimple? So wierd

Idk... #reefsquad got any ideas?

Odd, I have something similar that happen on a hydnophora frag, it looks like a pimple that is oozing. Sometimes it's black like it releasing waste, sometimes it's white. I'm definitely interested in what the #reefsquad has to say about yours.

Looks like cyano to me too. Have you tried to siphon it off?
