Species Overview

Atlantic Cod

The Atlantic cod is one of the most historically important commercial fish species. Its mild, flaky white flesh has been a staple food in Europe for centuries. Overfishing caused the collapse of the Grand Banks fishery in 1992.

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.
