The Jordans Catfish is Omnivorous and will accept virtually any food you can throw at it. They prefer live foods over all else but will happily receive chunks of frozen food or dried meaty treats.


It is difficult to determine the sex of Arius seemani without harming it.


Captive breeding is not common for the Jordans Catfish. In the wild the female lays approximately 100 and the male keeps them in his mouth for protection. Each egg is about the size of a small marble.


Jordans Catfish can live for more than 15 years if they are well cared for.


Arius seemani can be found along the pacific coast of North, Central and South America.

Short Description

Jordans Catfish is not a good species for the average aquarist to keep. This fish can get up to 2 feet in length so they require a very large aquarium to swim in. When young this catfish can live in freshwater but adults should be kept in brackish or salt water to avoid skin diseases. Unlike most catfish, these are not nocturnal; they will forage for food all day long. Be extra careful when handling this fish because their dorsal spines are poisonous if it punctures your skin.
