Yes, blue oscars are real. Blue oscars receive their coloration from meticulous crossbreeding practices. These beautiful fish have their scales lined with varying shades of blue, with the most common being a regal, dark blue.
Aside from their unique coloration, blue oscars also have gorgeous scale patterns that make them stand out from other oscars. The different shades and patterns of the scales help classify blue oscars into several variations.
With that said, be careful not to mistake blueberry oscars for blue oscars. Unlike blue oscars, blueberry oscars are painted fish. Blueberry oscars are typically albino oscars that have been dyed blue to make them appear more attractive.
In order to avoid buying a blueberry oscar by mistake, buy only from trusted breeders and stores that follow responsible, sustainable fishkeeping practices.
