Maracyn 2, clean water and a couple drops of colloidal.
He doesn't look so bad in the photos, but he just lays there. I only see him move at all when I move his bowl and he has to flutter his fins a tad bit to keep upright. Most of the time he's just laying on his side. His head is resting on a plant right now, and his snout is touching the surface of the water all the time so he doesn't have to go anywhere for air. He's also got more color than he did. His fins were all the tan that his body is.
I'm so glad he's hanging in there!
