Scientific Name: Astronotus Ocellatus
Average Adult Fish Size: 12 – 14 inches / 30.5 cm – 35.5 cm
Place of Origin: Oscars are native to Brazil, French Guinea, Columbia, and Peru and occur frequently in the Amazon River and surrounding basins.
Typical Tank Setup: A mostly open aquarium with some rock work. Large, well rooted plants like Giant Vallisneria, if kept protected by heavy rock work, will also work.
Recommended Minimum Aquarium Capacity: 55 gallon / 210 litre for one, 75 gallon / 300 litre or larger for a pair.
Compatibility: Temperament ranges from passive to mildly aggressive. Best if kept with other similar sized fish. Oscars will eat any fish that will fit in their mouth!
Temperature: 72 – 80 Deg. F / 22 – 27 Deg. C
Water Chemistry: pH 6.8 – 7.6 with ideal being 7.2.
Feeding: Flaked, frozen, and pelleted food when smaller, and larger pellets along with chunks of frozen food when larger. Oscars will eat live fish, but this is not the best diet for them as diseases are commonly introduced when using live feeder fish as food. Oscars diets can also be supplemented with krill, freeze dried shrimp, bloodworms, or vegetables like peas, lettuce, cucumber, zucchini. Like most fish, a varied diet is best.
Sexing: Males are usually larger and more colorful, but while these characteristics may help an experienced hobbyist, venting is the only sure way to determine gender with Oscars.
