Sciades seemanni (Arius seemani)
General Body Form:
The body is elongated and silver in color . The head is broad, with a large mouth. The eyes are large and protrude from the head. The Columbian shark possesses three pairs of barbels, one on the upper jaw and two on the lower area.
Not one of the most colorful of fish, the Columbian shark is a basic sliver in color with a white underside. The fins are black and white-tipped. The color contrasts fade with age.
Although sold as a freshwater catfish, the Colombian shark is best suited for the Brackish aquarium. Like most Brackish species, the young are more tolerant of water conditions than the adults. The water should have some sea salt added and measure a salinity of 1.005 to 1.015. The tank itself must be very large with good filtration and water movement. The tank can be decorated in dark colors with a thin layer of sand. Use rockwork to create caves and other hiding places. They are a predatory fish and should be housed with species that cannot be eaten. Feeding is not a problem as they will accept all types of prepared food. Sinking pellets, live insects, earthworms and small fish are some of its favorites. They have a voracious appetite and if not well fed will harass the other tank mates.
