Looks like HLLE, Head and Lateral Line Erosion. I believe it is caused by bad water quality, although there is speculation that it has something to do with running carbon.
Pics blurry. I don't see anything wrong. There's a white blotch on the side wich is usually blue, but it's so big it looks like the color. Everything looks good to me.
+2 beej.....nothing that a healthy diet and pristine water conditions can't fix I would think, but that looks really bad. But as long as he's eating, hopefully he can get better. What size is that tank? Can't tell by the shots, but it looks awfully tiny for him to be in.
Stupis iPhone for pics. But yea it's way to small for him. It's a 90 gallon. Some1 has it for sale and debating on buying it. I def wouldn't keep him in the tank if I buy it.
