Now he's at the surface of the tank gulping for air. Sadly I think he's about to depart.
He's in this tank 80 gall: 5 zebra danios, 9 neon tetras, 2 shwartz corys, 1 rainbow shark, 1 pleco, 6 serpae tetras, 1 flying fox, 2 clown loaches.
We've had a lot of sickness in there. The rainbow shark had fungus then shortly after we got that cleared we got the loaches who had ich. As soon as their ich cleeared up this danio showed up with what ever it is he has. It's very frustrating.
I'm going to try to post a pic of the sick danio.
