Iridescent Sharks

Native to Southeast Asia, Iridescent Sharks are a big commitment. Not only do they get large, but these fish are known to live 20 years or more! As a result, they’re regarded as species that only seasoned aquarists should keep.

If you ever see one of these fish in person, you might be confused as to how they get their name! Adult Iridescent sharks are usually solid dark gray in color. Truth is, that muted tone is something that forms slowly as the fish gets older. As juveniles, the Iridescent Shark is covered in dark shiny skin that shines in the light.

Aside from their color, these are very interesting looking freshwater sharks for your fish tank. They have that familiar catfish-like head complete with barbels. However, their bodies are quite bulbous. The fins are quite large and fan-like as well, giving the fish a unique profile.

Overall, Iridescent Sharks are not too fussy about their environments. They like temperatures between 72 and 79 degrees, standard pH levels between 6.5 and 7.5, and natural decor. That said, feeding can be a bit of a challenge.
