Description
The Pirarucu is one of the largest freshwater fish in the world, known for its massive size, distinctive large scales, and reddish-orange markings towards its tail. Native to the Amazon basin, it is an obligate air-breather that surfaces regularly for air. Due to its immense size and predatory nature, it requires expert care and extremely large, specialized environments.
