My Bolivian Ram has been acting a little strange lately. He's been staying on the opposite side of the tank than he usually does. And not that interested in eating, although he's eating a little. I can't tell if he has "spots" on him or not, but near his head/jaw area seems to be a little more gray than it used to. Can you tell anything by these pictures? He didn't move very fast when I put a bamboo stick in there either. I sure hope its not another case of columnaris.
