Oscar Cichlid

Oscar Cichlid (Astronotus ocellatus)

Maximum Size:

• Oscars can grow up to 12 to 14 inches (30 to 35 cm) in captivity.

Native From:

• Native to South America, primarily found in the Amazon River basin, including countries like Brazil, Peru, Colombia, and Ecuador.

How Big They Grow:

• In home aquariums, Oscars typically reach 10 to 12 inches (25 to 30 cm), though in the wild or under optimal conditions, they may grow a bit larger.

Life Span:

• Oscar cichlids live for 10 to 15 years, and sometimes even longer with excellent care.

Diet (Carnivorous or Omnivorous?):

• Oscars are primarily carnivorous, but they are also opportunistic feeders and show omnivorous tendencies. Their diet includes:

  • Insects, worms, small fish, crustaceans

  • Prepared cichlid pellets and occasional vegetables or fruits

Breeding Season:

• There’s no specific breeding season in captivity; they will breed year-round if water conditions are suitable. In the wild, breeding often coincides with the rainy season.

Best Tank Mates:

• Due to their size and aggression, tank mates should be chosen carefully. Best tank mates include:

  • Other large, robust fish such as Severums, Silver Dollars, Firemouth Cichlids, Jack Dempseys

  • Avoid small or slow-moving fish (they may be eaten)

  • Avoid overly aggressive species unless the tank is very large

Additional Tips:

• Oscars require a large tank (at least 55 gallons for one, 75+ gallons for a pair).

• They are known for their intelligence and can recognize their owners.

• Ensure excellent filtration — Oscars are messy eaters.
