I have a special little albino cory that has totally freaked me out 3x now. I say he is special since he is missing an eye and is the smallest fish I have. Since I'm dealing with high ammonia and possibly ick now, I figure it could be quite possible I may lose a fish. So one morning when this cory was stuck up against the filter I didn't really think anything of it and went in to get him unstuck and out of the tank. When I unstuck him.... He swam away.... Ok cool.... The next time he was laying totally motionless on his side (almost upside down) at the bottom of the tank. I went in to get him and after almost getting him in the net..... He swam away...... Same thing happened this last time. He is very active when not laying upside down on the bottom. Maybe he just totally wears himself out. *SLEEPING*
