Pretty sure it's zoa pox. Three day dip, 15-20min, and a four day rest. Continued if nessesary three day dip 5-10 min. I use reef pest solutions all out to dip.
im not sure if mine are zoa pox either. it still opens but not as big as it used to. these are utter chaos btw. a friend told me that the size of the utter chaos might be getting smaller due to it growing more polyps. I had some rastas that melted away from zoa pox not too long ago but it doesnt look like one. any have possible explanations? Thanks!
