Description
The Big-eyed Cachorro is a large, highly predatory freshwater fish characterized by its elongated, silvery body, prominent large eyes, and formidable, sharp teeth. It is an active piscivore, preying on other fish in its native South American rivers. This species requires a very large aquarium and specialized care due to its size and aggressive nature.
