It is starting to get an emaciated look .. you can see the forehead shrinking and the lateral line receding. The fin and tail erosion is most likely bacterial, When fish get this weak and don't eat enough, their immune system crashes.
I think that fishes best chance for survival is in a hospital tank.. treating the external bacteria can be done often with acriflavin at this point, or an antibiotic... I think your deworming strategy is good, but I think you will need to go longer with metro .
