"Introducing the vibrant Red Oscar! With its striking coloration and engaging personality, it's a standout in any aquarium."

Detailed Description:


  • The Red Oscar (Astronotus ocellatus), also known simply as the Oscar, is a popular and iconic freshwater fish prized for its bold red coloration and charismatic personality.
  • Originating from South America, particularly the Amazon River basin, Red Oscars have become a staple in the aquarium hobby due to their striking appearance and interactive behavior.


  • Red Oscars feature a vibrant red coloration with black markings and distinctive ocelli or eye spots on their flanks, which serve as camouflage in their natural habitat.
  • Their elongated, oval-shaped body and large, expressive eyes give them a commanding presence in any aquarium.
  • With their bold coloration and engaging demeanor, Red Oscars are a favorite among aquarists of all levels.

Water Conditions:

  • Optimal water temperature: 74-81°F (23-27°C).
  • pH range: 6.5-7.5.
  • Water hardness: 5-20 dGH.
  • Maintain excellent water quality through efficient filtration and regular water changes to ensure the health and vitality of Red Oscars.
  • Provide ample space and hiding spots to accommodate their size and territorial behavior.

Tank Setup:

  • Red Oscars require a spacious aquarium with ample swimming space and hiding spots such as caves, rocks, and driftwood.
  • Decorate the tank with sturdy plants and large rocks to create a naturalistic environment and provide areas for exploration and territorial marking.
  • Ensure the tank has a secure lid as Oscars are known to be strong jumpers, especially when startled.

Tank Mates:

  • Red Oscars can be kept with other large, semi-aggressive fish species that share similar water parameters and are compatible with their territorial nature.
  • Suitable tank mates include other large cichlids such as Severums, Jack Dempseys, and Firemouth Cichlids, as well as robust catfish species.
  • Avoid keeping them with smaller or more passive fish species that may become targets of aggression or predation.

Feeding Habit:

  • Red Oscars are voracious carnivores and enjoy a diet rich in protein.
  • Offer a variety of meaty foods such as live or frozen feeder fish, shrimp, earthworms, and high-quality pellets or flakes formulated for cichlids.
  • Feed them small, frequent meals to prevent overeating and maintain optimal health and growth.

Care and Maintenance:

  • Regular maintenance is essential to ensure the well-being of Red Oscars and maintain water quality.
  • Perform frequent water changes of 25-50% every week to remove waste and replenish essential nutrients.
  • Monitor water parameters using a reliable test kit and adjust as necessary to maintain stable conditions.
  • Keep an eye out for any signs of illness or stress, such as lethargy, loss of appetite, or abnormal behavior, and address any issues promptly.
