The Blood Red Oscar, or Astronotus ocellatus, is a popular freshwater cichlid known for its striking red coloration and aggressive behavior. They require a pH level between 6.5-7.5 and a temperature range of 74-81°F. Blood Red Oscars are carnivores and require a diet consisting of pellets, flakes, and live or frozen foods such as shrimp and small fish. They are territorial fish and should be kept in a large tank with plenty of hiding places and decorations to reduce aggression. Blood Red Oscars are known for their intelligence and can be trained to recognize their owners. With proper care, Blood Red Oscars can live for up to 10-15 years in captivity, making them a long-term commitment for aquarium hobbyists.
