Identifying and Understanding Aquarium Fish: Iridescent Shark and Other Catfish Species
As an SEO specialist for Google, helping digital content to be found and ranked on the search engine is one of my core functions. Today, we will explore a fascinating query posed by a user about a specific type of fish. This article will delve into the identification and understanding of the 'iridescent shark', commonly known as the Pangasianodon hypophthalmus, and other catfish species.
What is the Name of This Fish in the Link?
Iridescent Shark (Pangasianodon Hypophthalmus)
The image you linked appears to be a variant of the common goldfish or a young mirror carp, possibly even a koi carp. However, there is a distinct possibility of a different species captured specifically from your link. That blackish fish looks more like a type of catfish, known as the Iridescent Shark (Pangasianodon hypophthalmus).
Also called the black shark or black tiger shark, this fish is commonly found in Indian aquarium markets. Scientist refer to it by its scientific name, Pangasianodon hypophthalmus. The species name hypophthalmus is derived from the Greek words, hypo (underneath) and ophthalmos (eye), referring to the relatively small eyes, which are often observed.
Why Iridescent Sharks are Best for Aquarium Enthusiasts
It’s important to note that iridescent sharks are not recommended for beginners. These fish can easily outgrow most aquariums, potentially reaching lengths of 2 to 4 feet. They require a large tank, at least 7 feet long, or a pond for proper habitation. This species is one of the largest catfish in the world and, if improperly kept, can become a problem for the aquarium owner.
Natural Habitat and Behavior
Iridescent sharks are primarily found in the lower regions of water bodies, often in muddy environments where their sense of smell is highly developed, and their visual acuity is low. Despite their large size, they are generally gentle and peaceful in the right environment.
Farm and Consumption
These catfish are known for their taste and are commonly farmed as a food source in their native regions. They have been domesticated for this purpose and can also be caught from the wild. If you find that your tank becomes too small for these fish, they can be used in a more enjoyable way, such as preparing them for a meal.
Other Catfish Species: Clarias Batrachus (Magoor) and Clarias Garipinus (African Sharptooth Catfish)
Lastly, the image also brought up similarities with other catfish species, such as Clarias batrachus, commonly known as Magoor, and Clarias garipinus, or the African sharptooth catfish. The Magoor is typically black in color and never white, while the African sharptooth catfish is also never found in white, except in rare color forms.
Given these points, it is essential to identify the fish accurately for different contexts. If you actually saw the fish in a pond, and it is sometimes captured in aquariums due to its unique markings, it is crucial to understand that the specimen might not be the same when viewed in a captive environment. The natural behavior and markings of the fish can change in different environments.
For those looking to keep Iridescent Sharks or similar catfish, ensure you can provide a suitable environment and consider the long-term care required. Always do thorough research and consult with aquarium experts before making any purchase decisions.
