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.
Whale Shark
The whale shark is the largest living fish species, reaching lengths of up to 18 meters. Despite its enormous size, it is a gentle filter feeder that consumes plankton, fish eggs, and small fish by swimming with its wide mouth open.
