Species Overview
Northern Pike
The northern pike is an apex predator of freshwater lakes and rivers across the Northern Hemisphere. With its elongated body, duck-bill snout, and razor-sharp teeth, it ambushes prey with explosive bursts of speed.
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.
