Black Shark Catfish

General information

The Black Shark Catfish is a large freshwater fish species native to Southeast Asia, including the Mekong River basin. It is also known as the Iridescent Shark or Sutchi Catfish. It belongs to the family Pangasiidae, and is a popular food fish, as well as an ornamental fish for aquariums. 
The Black Shark Catfish has a long, slender body, with a forked tail and a dark, iridescent skin that shines in shades of blue and black. Its head is flattened, with a broad mouth and long barbels. It can grow up to 1.5 meters in length and weigh over 40 kilograms.

As a carnivorous species, the Black Shark Catfish feeds on smaller fish, crustaceans, and insects in the wild. In captivity, they can be fed a diet of commercial pellets, live or frozen meaty foods, and vegetables. It is important to ensure a varied diet to provide them with all the essential nutrients.

Males and females of this species are generally indistinguishable, but mature males may have thicker and more muscular pectoral fins, while females may have a rounder body shape.

Breeding the Black Shark Catfish in captivity can be difficult as they require specific conditions, including a large tank with adequate water flow, and a varied diet. Females can lay up to 10,000 eggs, which hatch after 24 to 36 hours. The fry can be fed with infusoria and newly hatched brine shrimp.

The Black Shark Catfish can be prone to bacterial and fungal infections, as well as parasitic infestations such as Ich. It is important to maintain good water quality and hygiene, and provide a varied and nutritious diet to prevent disease.

The Black Shark Catfish is native to Southeast Asia, including Thailand, Cambodia, Vietnam, and Laos. It is an important food fish in these regions and is also farmed for the international market.

The Black Shark Catfish is not recommended for beginner aquarium hobbyists due to its large size and specific care requirements. It can also be aggressive towards smaller fish and should be housed with suitable tankmates.

When introducing the Black Shark Catfish to a new aquarium, it is important to acclimate them slowly to prevent stress and health problems. The process can take several hours or even days, and involves gradually adjusting the water parameters and temperature of the tank.
