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.

Smallmouth Bass

The smallmouth bass is widely considered the best-fighting freshwater fish pound-for-pound. Found in clear, rocky streams and lakes, it is more athletic and acrobatic than its larger cousin, the largemouth bass.
