The Tiger Oscar Cichlid (Astronotus ocellatus) is a popular South American cichlid, widely recognized for its dramatic black body with vibrant orange-red markings. Native to the Amazon River basin, Tiger Oscars are intelligent, interactive, and often form bonds with their owners, making them highly engaging aquarium companions.
Tiger Oscars thrive in spacious tanks with strong filtration, as they are large and produce significant bioload. They are semi-aggressive and may be territorial with smaller fish, so it’s recommended to keep them with similarly sized tankmates. Their striking coloration and lively behavior make them a stunning centerpiece.
