Species Overview

Goliath Grouper

The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.

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.
