Species Overview
Bluegill
The bluegill is the most common sunfish in North America and often the first fish a young angler catches. Its deep body, dark ear flap, and iridescent blue-green colors make it easy to identify. A fierce predator of insects despite its small size.
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.
