Species Overview

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.

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.
