Description: This fish grows to be quite large and because of this is not suitable for long term aquarium use. Feed with sinking pellets. Use small grained gravel and do not use gravel with sharp edges. Hiding places are not required as the Salmontail Catfish usually spend their days swimming up and down the glass until feeding time. Care should be taken when handling this fish, as the sharp dorsal and pectoral spines are covered in a mucus that will irritate the skin. Can live in fresh or brackish water. This is a nocturnal species that will be far more active at night.
