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.
Red Snapper
The red snapper is one of the most commercially valuable reef fish in the Gulf of Mexico. With its distinctive rose-red body and pointed anal fin, it inhabits rocky reefs and artificial structures at depths of 10-190 meters.
