Aquarium Fish

Redtail Catfish

The Redtail Catfish (Phractocephalus hemioliopterus) can get up to around 50 inches (130 cm) or larger in size when fully grown! The more commonly seen sizes are around half that - 25 inches (65 cm) or so. They are considered fast growers and will outgrow 99 percent of home aquariums so it's best to not buy this catfish unless you have a large backyard pond to put them in. The redtail catfish can live for many, many years so putting one in a small tank that they can quickly outgrow is not a good idea at all.

The Redtail Catfish is a good eater and it's recommended to feed them a couple of times per week with meaty type freshwater foods or catfish sticks or the larger pellets. They will eat smaller tank mates.
