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). This was done 2005 during my attendance of Aquarama 2005. I share my experience with some small interviews with Pauline Yong (daughter of original owner, Teo Way Yong). Unfortunately this breeder & exporter closed there business several years ago.

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.

Antibiotics are effective for control; however, accumulating evidence indicates that unrestricted use of antibiotics harms fish, human beings, and the environment. Thus, finding safe, efficacious, cost-effective, and environmentally friendly substitutes is of great interest. Reports showed that dietary supplementation with functional additives with health-promoting and immunostimulatory functions could be a promising strategy. Herein, we provide an overview of the non-antibiotic feed-based strategies for combating Red Mouth bacterial infection (Yersiniosis) in Rainbow Trout without resorting to antibiotic usage. For this issue, the uses and application of some vitamins, probiotics, prebiotics, synbiotics, quorum quenching probiotic strains, algae, or organic acids, are included in the article
