Description
The Redtail Catfish is a massive, predatory freshwater fish known for its distinctive red-orange caudal fin. Native to the Amazon and Orinoco basins, it requires an extremely large aquarium or pond due to its potential to grow over 4 feet long. This species is a true carnivore, consuming smaller fish, crustaceans, and insects in the wild.
