Iridescent sharks (Pangasianodon hypophthalmus)

Iridescent sharks, also known by their scientific name Pangasianodon hypophthalmus, are fascinating and stunning freshwater fish sometimes nicknamed "freshwater sharks" due to their appearance and behavior. Although they are not related to true marine sharks, their elegant look and dynamic behavior sometimes recall these ocean predators.

These fish are distinguished by their streamlined bodies, smooth skin, and silvery coloration, with iridescent reflections that shimmer in the light. Their unique appearance adds a touch of exoticism to any freshwater aquarium, captivating viewers with their metallic sheen.

Unlike true sharks, iridescent sharks are peaceful fish that behave well in community aquariums. They are gregarious by nature and are often seen in small groups, gracefully swimming through the water. Their peaceful behavior makes them ideal companions for a wide variety of other freshwater fish species.

To keep them in captivity, a spacious aquarium is necessary, with plenty of room for free swimming. Iridescent sharks also appreciate the presence of hiding places, robust live plants, and rocks for shelter and exploration. Regarding water parameters, they prefer a moderate temperature between 24 and 28 degrees Celsius and slightly acidic to neutral water.

In terms of diet, iridescent sharks are voracious omnivores that accept a variety of foods, including pellets, flakes, frozen foods, and fresh vegetables. They are also fond of live prey such as bloodworms and small crustaceans.

In conclusion, iridescent sharks are beautiful and captivating freshwater fish that bring a touch of exoticism to any aquarium. With proper care and a suitable environment, these fish can thrive and provide aquarium owners with years of enjoyment and fascinating observation.
