So, I got this kole tang about a month ago. I think he was sick from the start...showing ich spots the day after I got him home. But then they went away and he was swimming around and eating all the algae off my rocks and pellets soaked in garlic. Two nights ago I noticed that his mouth was always open and seemed fuzzy and swollen. I researched it and it seems others had this and it was a mouth fungus. He died the next night. What I am wondering is should I be worried about my other fish, I have a firefish and a goby/pistol shrimp pair. I don't have a hospital tank
