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.
白梭吻鱸
The zander is the European equivalent of the walleye and one of the most prized freshwater predators in Europe. Its excellent low-light vision makes it a crepuscular hunter. Its delicate white flesh is considered among the finest of freshwater fish.
