Basic “must know” information about Oscar fish:

Scientific name: Astronotus ocellatus
Maximum size (min-max): 30.0 - 40.0 cm (11.8 - 15.7 inches). They’re often sold as small specimens that hardly reach 2.5 cm (approximately 1 inch) in length, however Oscars can grow as fast as 2.5 - 5 cm (1 - 2 inches) per month until they reach 20 cm (roughly 8 inches) when their growth rate slows down by 50%.
Recommended temperature: 24.0°C - 30.0°C (75.2°F - 86.0°F) - Oscars aren't coldwater fish!
Recommended water hardness (dGH): dGH 4.0 - 18.0 N
Recommended pH of water: 6.5 - 7.5

Origin: South America; Click the link: South American Whitewater River if you'd like to build a biotope aquarium for these fish
Water quality: Ammonia, nitrites should be nil; Amount of nitrates can be as high as 40 ppm (40 g/l), however never introduce this specie to an uncycled tank!
Average lifespan: May vary between 10-18 years, however many specimens have lived for over 20 years.

It's a vacuum cleaner brand that is better than a Kirby but not as good as the one with the ball (and plastic parts).
