The Oscar fish (Astronotus ocellatus) is a popular freshwater species, often found in the Amazon and Orinoco basins. It is known for its vibrant coloration and distinctive body patterns, which make it a favorite among aquarists. Oscars are hardy fish, capable of thriving in various water conditions, but they require ample space due to their territorial nature. Anglers also appreciate them for their game qualities, although they are more commonly associated with the aquarium trade.

Oscars prefer quiet, shallow waters with muddy or sandy bottoms, such as canals and ponds
They are primarily benthopelagic, staying close to the bottom but moving freely through the water column
Their diet includes small fish, crayfish, worms, and insect larvae, making them opportunistic feeders
Oscars are territorial and require environments with hiding spots like rocks and vegetation
In the wild, Oscars typically spawn during the rainy season, when water levels rise
Both parents participate in cleaning a flat surface, often a rock or branch, for egg deposition
After hatching, the fry are moved by the parents to a safer, shallow pit in the substrate
Parental care continues until the young are able to fend for themselves, with both male and female guarding the offspring aggressively
