Something is irritating my zoas

[James Macaluso]

Hello everyone!
I saw that my frag of Sunny D's has been a little ticked for a few days now. Found some white hairs growing in it. Never have seen them before. I included some pictures of them under good light from the top and side. I have about 15 other colonies I really fear this may spread to. If you happen to know what this is, please let me know

Thank you,
James

Possibly hydroids, I'd try a dip but unsure what would work best.

Looked them up. I think its definitely hydroids. Thank you so much. I think it was a flow issue

Bummer, but great photos of your issue. Gl

I did a R/O Dip with a little iodine and the hydroids peeled right off. They formed a clear "skin" over the polyps and were very easy to remove. Cranked the flow over the frag rack as I realized that it was virtually stagnant up there. Will get a cross flow gyre real soon.

That's definitely a great pic of what was going on.

Did they open up after the dip? What kind of iodine ?
