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.

Summer Flounder

The summer flounder, or fluke, is a flatfish that lies camouflaged on the ocean floor. Born with eyes on both sides, one eye migrates to the left side during development. An ambush predator, it explodes upward to grab passing prey.
