There was a post from years ago regarding a "mystery disease" on a Powder blue tang. After scouring the internet trying to figure out what this is...I stumbled across this photo. This is exactly what I have on my blue. There was no real useful info in this thread as to what it is and how to treat. Can anyone help me? This is the photo from the thread.(in the pvc tube) top photo is my powder blue. Shes been like this for over a week now. Doesnt look like it's getting any better. I dont know what to do for her.
