The Red Oscar is an intelligent, hardy fish. They are quite hardy and can adapt to a wide array of environments. It is important to remember that the Red Oscar requires a large aquarium of at least 70 gallons and a deep sand bottom with a few large rocks. Additionally, it is important to remember that they will dig up plants, so any in the tank should be potted with the root surfaces covered with rocks. Floating plants are a great solution to this problem. With their small size, they form a tight cluster for protection, which is normal behavior for juvenile fish. Large Oscars, once full grown, are not as territorial as other cichlids, but they will consume anything they can fit into their mouths.
A large tank of at least 100 gallons is the best choice for breeding Red Oscars. It is important that the water is clean, clear and has a temperature between 79-86°F. The female will lay between 1,000-2,000 eggs on rocks that have been carefully cleaned, which will turn transparent in 24 hours. To make sure the brood is properly taken care of, the fry should be kept in pits and sometimes even covered. When the fry are free-swimming, they will need to be fed Cyclops to ensure proper growth. Furthermore, the fry may even cling to their parents for protection.
The Red Oscar is a carnivore that is known for its hearty appetite. Oscars are known to eat a variety of meaty foods, including small fish and earthworms, Cichlid pellets, larger flake food, ocean plankton, bloodworms, and tubifex worms.
