Species Overview
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.
Red Drum
The red drum, or redfish, is an iconic inshore game fish of the Atlantic and Gulf coasts. Identified by the distinctive black spot at the base of its tail, it feeds by tipping head-down in shallow water, exposing its copper-colored tail.
