I might have found a way to get pictures uploaded, so I'm giving it a try.
This first one is of him listing sideways and having trouble staying upright. I took it last night before starting the epsom salts.
Here he is this morning. He's got a bit more color back in him, but still no poop on the tank floor. You can kind of see where his stomach bulges downward by his fins.
The last is of him from the top. I don't see scales sticking out, but I've never dealt with a sick fish before, so he might seem different to you.
