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. An aquarium of around 700 gallons minimum is highly recommended. Once established these fish are quite long lived, reaching the ripe old age of 20 or more!  You can check out the Redtail Catfish in the video below... 

Redtail Catfish go by several different names including the South American Red Tail Catfish, Cajaro and Pirarara. These freshwater fish have a very wide mouth and a body that is dark gray with a white band that runs around the lower half of their bodies. They have three pairs of long barbels as well, which is a trait shared by all the Catfish in the Pimelodidae family. As you can see, they get their name from their caudal fin or tail which is red. When this fish is younger its colors tend to be more intense.

Redtail Catfish are omnivores that should be fed a variety of foods including fruits, crustaceans and fish. Watch out, this fish will pretty much eat anything that it can fit into its mouth. Be careful with other tankmates, and even objects in the tank. They will often eat decorations and then regurgitates them. As you can imagine, this is not very healthy for the fish. Be careful not to overfeed them as well, once a week should be fine.
