Description
Oscars are large, intelligent, and charismatic South American cichlids known for their striking patterns and interactive personalities. They are popular aquarium fish but require significant tank space and robust filtration due to their size and messy eating habits. Their temperament can range from relatively peaceful to highly aggressive, especially during breeding.
