Redtail Catfish (Phractocephalus hemioliopterus)

The Redtail Catfish or Phractocephalus hemioliopterus is a large species of Catfish that was first discovered in South America. This fish has since made its way into the aquarium trade, despite its very large size. Reaching 4' and almost 100lbs in the wild, these fish should only be kept in a VERY large aquarium. Due to the lack of space in most aquarium settings, these fish rarely reach over 2' in length in captivity.
