I think I may be loosing a fish and i'm not sure how to treat it! :-( I checked my tank this afternoon and was observing everyone after feeding when I noticed one of my dwarf gouramis was not eating and was VERY bloated. I immediately moved him to a quarantine tank (I keep a small 2.5 gallon tank cycled for instances like this). As I was observing him I noticed red streaks on his side. I have no idea how to even begin treating this! I thought maybe it was a slight case of swim bladder disease but as the day progressed it got much worse and the red streaks showed up. I'm treating right now with Pimafix and am observing him. he seems to be doing a little better, but he is still very swollen. Any suggestions on what it may be? How to treat it? Or should I just let him die in peace? 

Attached are pictures from when he appeared to be at his worst. As you can see from the photos he was in a small fish bowl while I was relocating my hospital tank to an area where i could observe it all day long. I wanted to snap the photos while it as out and in a shallow bowl.
