So about a week ago my uncle caught a couple 4-10 lb channels from the lake and threw them into my dads pond. About 2 days later one of them was next to the bank, barely alive and was bright yellow all over. Has anyone ever heard of this and what could it be? SO far none of the other cats and no other fish have done the same thing so i dont thing it was a disease or anything. HE took it out though. I wish he wouldve got a picture cuz ive never heard of anything like that.
