Well Darwin still spends all his time bottom sitting
He's not gasping or flashing, there are no outward signs of anything wrong, but he hardly swims. Every time I walk by the tank I check to see if he's alive.
In the lfs he was really active but it was hard for me to observe him in QT with the dark plastic tub and heavy surface agitation, but I do think he was sitting a lot in there too.
I'm not sure what to do. I don't want to remove him and QT him again, but he's certainly not right. I think I'll give him another couple of days and observe him carefully then decide on what to do.
