Arius leptaspis can grow up to 32 inches, keeping these fish long term is not practically possible cue to the size of the tank required. It is advised that these fish should not be purchased unless you have a very large aquarium to house them when they reach their adult size. They will tolerate brackish or freshwater conditions and spend all day swimming up and down in the aquarium. Due to the fleshy make up of their skin it is advised that any gravel added to the aquarium should be rounded, any sharp edges will easily injure these fish and the wounds may lead to infections in the long term. Salmontail catfish are mostly nocturnal but care must be taken when handling them. They possess a sharp spine on their dorsal and pectoral fins; also they are covered with mucus that is irritating to the skin. Although the Salmontail Catfish is classed as peaceful, they will attempt to eat smaller tankmates and as they mature this problem will increase due to their large size.
