Yeah, I was aware of that... I have very little free ammonia and my total ammonia is bouncing from .25 to .5 so the bio filter still needs to mature quite a bit. It's the start of the 6th week and he's still not the same, but then again, I did add about 170 new gallons and a lot of new gravel. I just hope this is the end game. He is better and eating again, so I count my victories.
