Clownguy...
Like I said, mine only lays down to sleep at night. Umm, the only thing that looks off to me is your ammonia. As I am sure you know, it should be zero. Have you added anything else new to the tank or moved anything around recently?
Maybe you can do a water change to try to get that ammonia back down to zero.
I wouldnt worry too much as long as she is eating and swimming good.
Does anyone else have some advice?
