In this article, we will explore the distinct characteristics of various types of Arowana fish and delve into their physical attributes, geographic distribution, and endangered status.
Description of Arowana Fish
Arowana fish possess an almost eel-like elongated body, which contributes to their distinct appearance. Their dorsal and anal fins are short, soft, and extremely elongated, resembling an extended tail fin. Different species of Arowana fish exhibit a variety of colors, ranging from silver to blue and red[1]
Asian Arowana
The Asian Arowana, scientifically known as Scleropages formosus, is a species that comprises several phenotypic varieties distributed across Southeast Asia[2]. While many consider these varieties to belong to a single species, the work by Pouyaud et al. (2003) differentiates them into multiple species[8].
Jardini Arowana
The Jardini Arowana stands out with its golden-brown scales, intricate markings, and elongated body. These fish are recognized for their strong jaws, which they use to seize their prey with great gusto. If you’re seeking a fish with a powerful presence, the Jardini Arowana might be the perfect choice for your aquarium[3].
Batik Arowana
The batik Arowana showcases a distinct appearance with its batiked scales, creating a unique and captivating effect. These fish can grow up to 35 inches long and live for up to 20 years with proper care. Their diet primarily consists of insects, crustaceans, and small fish, and they thrive in water temperatures ranging from 78°F to 82°F[4].
Endangered Status of Asian Arowana
The Asian Arowana is considered an endangered species and is banned in the United States[5]. It has become a symbol of wealth among wealthy Asian individuals, with some specimens fetching record prices at auctions. Most pet Arowana fish are bred in captivity behind high-security fences, as these fish prefer solitude and may exhibit dominance and aggression in adulthood[5].
Arowana Fish Uniqueness
Arowana fish possess several unique traits that contribute to their distinctiveness. One of these traits is their bony lower jaw, which has earned them the nickname “bony tongues”[6].. This feature sets them apart from other fish species and adds to their overall allure.
Suitable Tank Size for Arowana Fish
Due to their large size and active nature, Arowana fish require spacious tanks to thrive. The minimum tank size for a solitary Arowana, with possibly a few tank mates, varies depending on the species. For South American Arowanas, a tank size of at least 220 gallons (6′ x 2.5′ x 2′) is recommended, while for Asian or Australian Arowanas, a minimum tank size of 120 gallons (4′ x 2′ x 2′) is sufficient[7].
Conclusion
The distinct appearance of Arowana fish makes them a captivating choice for aquarium enthusiasts. Their elongated bodies, unique colorations, and striking features set them apart from other fish species. From the Asian Arowana with its geographic distribution and endangered status to the Jardini Arowana with its golden-brown scales, each type of Arowana brings its own charm to aquariums worldwide. Providing adequate tank size and care is essential to ensure the well-being of these remarkable fish.
