I was wrong. We did a blood test and hemoglobin level was ok. I don't know for the other values which show High and Low.
I asked about "Gran' he said thats the level of bacteria cells in the blood. He said it should all recover once she get proper food, movement, less stress ect.
For the rest she was fine.

Jack, he says he's been giving vitamin/mineral tablets and fed kibbles once a week. The fish was cleaned and frozen -25.

Here are the results of the bloodtest.
Will repeat in 6-8 weeks.
