This started out as one scale protruding out like maybe a wound, and a couple days later it looks like this. We have him in a hospital tank right now doing Fungus and Parasite treatment with Maracide and Maroxy. In just 2.5 days there is white stringy lookin stuff all over the inlet of the filterand I notice when he moves fast small peices of it fall off. From the best I can tell he hasn't eaten in the last couple of days either. He is swimming ok, not floating or tilting. He still comes to the glass when I am around like he did in my main tank.
