strange zoa behavior


New member
came home today, and i found these long, brown, skinny strings coming out of the center of some of my zoa polyps! is this normal?

sounds like cyano bacteria to me. I would immediately remove as much as you can and aim some flow to it. There are some other steps you need to do but I am unaware of them so I will leave it to another reefer to inform you!

that could be zoa poop. Mine exhibit that behaviour a few hours after feeding (on the rare occasion I get around to feeding them)

Of course it could be other things also...a pic would be most helpful :)
