In this video, personally recorded, we visited one of the oldest and largest export facilities of ornamental aquarium fish in Singapore (Teo Way Yong, founded in 1963).

The bacterial infection (especially in the gills) is killing the Oscar Cichlids (Astronotus) and should be treated with anti-bacterial medication, such as antibiotic (ask your fish doctor).
Few gill flukes, left over from previous treatments: I would not treat now since 2x treatment was executed.
But keep an eye on the evolution of these gill flukes and maybe apply another kind of anti-fluke treatment.
The gill flukes caused the damage to the gills and are the cause of bacterial infection.
