Freshwater Shark

Freshwater sharks, commonly referred to as freshwater shark catfish or simply freshwater sharks, are a group of fish species that have a similar appearance to sharks but are not true sharks. These fish belong to the family Pangasiidae and are native to Southeast Asia. Here’s a description of freshwater sharks:

Appearance: Freshwater sharks have a streamlined body shape with a flattened head and a long, slender tail. They have a distinctive shark-like appearance, characterized by a large, upward-facing mouth and rows of small, pointed teeth. Their bodies are typically covered in rough, sandpaper-like skin, which adds to their resemblance to true sharks. The coloration of freshwater sharks varies among species, but it often includes shades of gray or brown, with some species displaying mottled or spotted patterns.

Size: Freshwater sharks can vary in size depending on the species. Some species, like the Iridescent Shark (Pangasianodon hypophthalmus), can grow quite large and reach lengths of up to 3 to 4 feet (90 to 120 cm). Other species, such as the Redtail Shark (Epalzeorhynchos bicolor), are smaller and typically reach lengths of around 4 to 6 inches (10 to 15 cm).

Behavior: Freshwater sharks are generally peaceful fish, although some species can exhibit territorial behavior as they mature. They are bottom-dwelling fish that spend much of their time scavenging for food on the substrate. Freshwater sharks are known for their strong swimming abilities and can cover large distances in the aquarium. Some species, like the Iridescent Shark, are known to be migratory in their natural habitat.

Water Requirements: Freshwater sharks are adapted to tropical environments and require specific water conditions to thrive. They prefer water temperatures between 75°F and 82°F (24°C to 28°C) and a pH level around 6.5 to 7.5. Adequate filtration and regular water changes are necessary to maintain good water quality and ensure the health of these fish.

Feeding: Freshwater sharks are primarily omnivorous, although their diets can vary depending on the species. They are opportunistic feeders that will scavenge for food on the substrate and also consume small aquatic invertebrates, worms, and insect larvae. In captivity, they can be fed a diet of high-quality sinking pellets, frozen or live foods like bloodworms, brine shrimp, and small pieces of meat or vegetables.

Aquarium Setup: Freshwater sharks require spacious aquariums due to their active swimming behavior.
