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.

Yellowfin Tuna

The yellowfin tuna is a pelagic predator found in tropical and subtropical oceans worldwide. Capable of speeds exceeding 75 km/h, it is prized both as a sport fish and for its high-quality sashimi-grade flesh.
