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.
Tarpon
The tarpon is often called the 'Silver King' for its large mirror-like scales and acrobatic leaps. This ancient species has existed for over 100 million years and can breathe air using a modified swim bladder.
