Average lifespan
Oscars can live around 10 to 15 years.
Size
Oscars are relatively large freshwater fish, with adults reaching lengths of up to 30 to 35 centimeters (12 to 14 inches) on average.
Weight
Adult Oscars can weigh anywhere from 1 to 2 kilograms (2.2 to 4.4 pounds).
About
Oscars are native to South America, particularly found in the Amazon River basin and its tributaries. They inhabit slow-moving rivers, lakes, and flooded forests, where they can find suitable food and shelter.
Size and behavior
Oscars have a deep, oval-shaped body and are known for their vibrant coloration and distinctive markings. They are territorial and aggressive fish, often defending their territory from intruders and competing for food. Oscars are also intelligent and can recognize their owners, displaying interactive behavior such as begging for food and following movements outside of the tank.
Diet and nutrition
Oscars are carnivorous predators that feed on small fish, crayfish, insects and other invertebrates. In the wild, they hunt in slow-moving rivers and flooded forests of the Amazon, using a sudden burst of speed and their large mouths to suck in prey.

Conservation status
The conservation status of Oscars in the wild is not evaluated separately, as they are considered a species of least concern by the International Union for Conservation of Nature (IUCN). However, they may face threats from habitat destruction, pollution, and overfishing in some areas of their range.
Fun fact
Oscars have a distinctive eyespot, a dark spot ringed with orange, near the base of their tail. Scientists think it helps protect them by confusing predators, and it may even discourage piranhas from biting their fins.
