"This tall, dark fish lives on the fruit falling from trees, some of which have hard shells. Its extremely strong jaws allow it to break shells and extract the fruit."
The Tambaqui can be found throughout the majority of the Cortica River's Midstream section.
These fish swim about slowly and keep mostly to themselves. They are mixed in with the other fish seen in the river and are not aggressive towards the player, though they could potentially pose a threat if they were as their in-game information remarks upon their powerful jaws.
- In real life, the Tambaqui is a common fish in aquaculture (the farming of aquatic organisms for food or other purposes) because it can live in mineral-deficient waters, is very resistant to disease, and change in the pH of their environment does not affect them until the change reaches extreme levels.
