About a week ago, I noticed that my calico ranchu was starting to act strange. He would sit at the bottom almost motionless at certain times. I noticed it the most right after feeding time. It seemed like he had a hard time digesting or something. His appetite is still very good and he is active when i bug him. About 3 days ago, i found him wedged between a piece of driftwood i have and the side of the tank. I decided that it was time to take some action, so i put him in a quarantine tank and salted to .3%. He started to look better after about 12 hours. After 3 days in the quarantine tank he is still not back to normal, but better than before i stuck him in the quarantine tank. He sits there in the bottom until i bug him or its time to eat. Should i treat him with something else?
The only thing i can see that is outwardly wrong with him is that one of his eyes maybe a little cloudy. What should i do?

lets hope he is not infected with internal bacteria...

and you probably have overfed him that makes him feel uncomfortable..

try fasting him for a day, then feed peas..

I already tried that, it didn't work.
He now just sits on the bottom until i bother him or its feeding time. How do u get rid of internal infections? Medigold?
