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. It should be much more dificult to acquire this fish since it is mostly inappropriate to stock except for in the rarest of conditions. The redtail catfish can live for many years so putting one in a small tank that they can quickly outgrow is not a good idea at all. Pet stores will not usally take them back either. Buyer beware.

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. There are videos online of people feeding them feeder fish and this is not recommended. Feeder fish can carry all sorts of disease and parasites, not to mention the cost of feeding live fish versus a good quality catfish pellet or flake food.

Breeding them in the home aquarium is not common at all given their potential adult size and because you cannot determine differences externally of males and females of this catfish.

Even after reading all of the above and if you are still interested in keeping them be ready to get an aquarium or pond in the 1,000 gallon size range along with massive filtration. They are big eaters and frequent partial water changes will be needed as well.
