Species Overview
Muskellunge
The muskellunge, or 'muskie,' is called the 'fish of 10,000 casts' due to its elusive nature. The largest member of the pike family, it is a powerful ambush predator found in clear lakes and rivers of the northern United States and Canada.
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.
