Description
The Oscar Cichlid is a large, intelligent, and popular freshwater fish known for its distinctive eye-spot on the caudal fin and varied color patterns. They are highly interactive with their owners but require a substantial tank due to their adult size and significant waste production. Oscars can be territorial and aggressive, especially towards smaller fish.
