Oscar
Not consumed — popular ornamental cichlid kept for its bold patterning and personality; occasionally eaten in parts of South America but primarily an aquarium species.
Species Overview
Common Carp
The common carp is one of the most widely introduced freshwater fish globally. Originally domesticated in East Asia over 2,000 years ago, it is a sacred fish in many cultures and the primary target species in European coarse fishing.
Oscar
The oscar is a large, intelligent cichlid native to the Amazon basin. Known for its dog-like personality, it can recognize its owner and may beg for food. Oscars rearrange their tank decor and require spacious aquariums with robust filtration.
