You're theorizing the carrier thing happening with Anemones.
The only things that have been reported consistently that happen with nems is chemical warfare or not QTing a new one and introducing infection into a tank. As I mentioned previously if you have proof otherwise I'd love to be educated, but I'm not going to sit here and back and forth with you about theories when I have spend days upon days testing and trying multiple different things myself personally, not to mention all the work I picky-backed off of Minh and all the work others have done. I'm not talking about just Theory. I'm talking about things that have been actually documented multiple times and places.
