What do you think this is?

See the strand growing out of the middle of this coral? Any idea what it might be? Should I be concerned?

Could be poop, could be a sweeper (although I usually do not see sweepers that long on a candy cane). How long has it been there? I would only be concerned if over a day.

Just saw it this afternoon. It wasn't there yesterday.

Monitor, likely just poop.

 

[Cool Fish]

Huh. Interesting. "Gone Reefing" suggested the same thing. Never saw this before.

Expelling waste.

 

[Cool Fish]

Looks unanimous! Thanks guys!

Well, I just checked again...and it's gone! So, I think you guys were right! Thank you!
