ok so today i looked in my tank and my rabbitfish had fifteen white dots/spots all over it. Recently a kole tang has disappeared and a cleaner wrasse as well. neither showed any signs of disease before except for mabe the kole tang who lost all its color before it disappeared. I was told it was likely ii added a sick fish. It may be true but none of the recent ones i added looked diseased. I added a aurora/pinkbar goby and pistol shrimp three days ago but i dont think it would affect everything so quickly. I do not have a qt. One of my clownfish has one white dot on its tail which may or may not be related. Any ideas how to fix this without killing all my coral/inverts.
