What is this?

Happy Holiday all!

 

 I bought some live rook yesterday and found this in the styrofoam container. I belive it's a bristle worm. Never seen one this color before.

Thanks,

Definitely a bristle worm.  Not sure why it's so red.  Maybe a fire worm?  There's one way to know for sure.

I'd have Tim come over and poke it with his fingers if you have any doubts.

And great to see you online Dave!  How's the tank doing?

Aaahhmm, I'm not that good of a friend.

Tanks is going through a cyano break out. we thought we had it licked but ti came back with a vengance. Need to run some tests!

I periodicly see cyano pop up.  sometimes it's associated with a stress event that disrupts the corals.   It can be a sudden drop in alkalinity or a sudden change in average temp (> 5°) or an unexpected coral death.  And it can be several weeks after the event.
