Yellow polyps turning GREEN?

[hesstondc]

Recently the stalks of a few of my yellow polyps are turning very green in color....Is this a disease or is it like of iodine or something...I use a dose that contains iodine but it may not be working or something....

They look healthy and all of them open but the color is just off....

Anybody know what this is?

Thanks

How much iodine are you dosing? Not very much is needed and this could be affecting the polyps. Have you changed anything else lately like lighting?

Never heard of this before. Probably fluorescing proteins, though, and probably light related. I doubt its a disease, and I do;t think they use or need iodine at all.
