Species Overview
Angelfish
The freshwater angelfish is a majestic cichlid with a laterally compressed body and long, flowing dorsal and anal fins. Native to the Amazon basin, it has been selectively bred into numerous color varieties including marble, koi, and platinum.
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.
