Arowana, a very old fish origin is called Arowana, which means "long tongue" in Spanish.Its scientific name is "scleropages" which means pharyngeal tongue and skull.According to taxonomy, arowana belongs to the family Bonytonidae (also known as Bonepharynidae).It is called "Dragon Fish" in mainland China, "Dragon Ball" by Hong Kong people (probably due to the yolk sacs of dragons like dragon balls), Taiwan people call it "Silver Belt", Japanese people call it "Silver Sword".
Osteopharynx fish are produced in four places: Asia, South America, Australia, and Africa.Mainly produced in: Indonesia and Malaysia.
Bone-pharyngeal fish in Asia include: red dragon, golden dragon, orange-red dragon, platinum dragon, pepper red dragon fish.
Red Dragon: Scientific name: Scleropages formosus English name: Red Arowana is also called Red Golden Dragon.This fish is protected by the Washington Convention as an endangered species.The body color of its juvenile is lighter, white and reddish, and its scales are small.But the adult fish has a huge body, with strong dark red on the edge of the gill, so does the tongue, the edges of the large scales and the fins also have strong brilliant red stripes, and the golden scales sparkle.It is a large fish with great ornamental value.
Golden Dragon: Also called Golden Dragon English name: Golden Arowana.Its back is a dark green scale frame shining with golden light. The cheek is different from the red dragon. There is no red but a bright golden yellow.
Platinum Dragon: English name: Platina Arowana.Its shape is similar to that of a red dragon. The color of the scales is platinum.
Qinglong: English name: Green Arowana.Body shape is shorter than other Asian arowanas.The cyan lateral line of the scales is clearly developed.The most precious ones are purple scales with scales.Can be reproduced artificially.
Jinbei: English name: Belly Arowana.The extremely expensive arowana is very similar to the golden dragon except that its golden scales cross the dark green back to wrap a golden shell on the whole body.
There are two types of Arowana in Australia: Star Dragon and Star Dragon:
Scleropages Leichardti: It is produced in eastern Australia and is similar to the star-pointed dragon. The juvenile fish is very beautiful, the head is small, the body has many red star-shaped spots, the anal fin, dorsal fin, and tail fin have golden yellow star spotsStriped, the body color of the adult fish is silver with a beautiful yellow, the dorsal fin is olive green, and the belly has a silvery luster.Each fin has black edges.Is a nocturnal fish.In recent years, the Australian government has stocked this fish fry in large numbers, so the number will not be small.
Scleropages jardini: Produced in northern Australia and New Guinea. It has a smaller body with a sharp mouth and a silvery gold color with a half-moon-shaped scale. It has a few gold edges on its cheeks and golden markings on its dorsal fin.Breeding is easy and can be reproduced artificially. Australian arowana There are three main species of fish in the family Bonefish in South America: silver dragon, black dragon, elephant fish (also called walrus, giant bone tongue fish)
Silver Dragon: Osteogloxssun bicirrohomus is produced in the Amazon Basin in Brazil.It was first discovered by the fish scientist Vandelli in 1929.It is a local food fish.Introduced to the United States in 1935.Introduced in Japan in 1955.In 1966, Mr. Miyada of Kobe, Japan, first used artificial hot springs to successfully breed hot springs in a tropical farm in Aso Changyang, Kyushu.However, the artificial reproduction introduced by South America through the re-export of the United States is rarely seen in the Chinese market.The fish scales are huge and pink semi-circles, and the fish body looks like metallic silver, which contains cobalt blue, blue, cyan and other colors mixed and shiny.The dorsal and anal fins grow backwards with long bases, short caudal fins and large pectoral fins.
Black dragon: Osteogloxssun ferreirai is almost the same shape as the silver dragon. The adult fish is silver, but when it grows up, it will tend to be black with purple and cyan, and gold bands.Very ornamental value.Juveniles have obvious black body patterns with yolk sacs hanging under their pectoral fins, so Hong Kong people call them black dragon spit beads.
Elephant fish: Arapaima pirarucu is produced in Colombia and Brazil.The gigantic body can grow up to 5 meters long.It is used as food fish in its place of origin.In recent years, due to the sharp decline in quantity, the local government has banned fishing and trafficking, and even more, it has been denied export.I only saw a two-meter long elephant fish in Wuhan New World Aquatic Park.The body is black, and the scales have an orange-red frame.It is so powerful that it makes a loud noise when its tail sweeps to the glass wall of the aquarium.
There is only one species of African bone tongue fish called Nile Arowana Heterotis niloticus distributed in the upper and middle Nile and tropical West Africa.The shape is similar to Asian and Australian arowana.The contour from the end of the kiss to the front of the dorsal scale is not linear. In addition, the mouth is large and does not crack.The body color is olive with gray instead of black, and the Nile Arowana in natural waters can be up to one meter long and weigh 6 kg.It can grow up to 80 cm in the aquarium.It should be noted that this fish does not eat small fish but eats plankton, such as worms, red worms, etc. Is it interesting for such a huge fish to eat such a small thing?The upper part of its fourth and fifth cheeks is a spiral respiration resembling a labyrinth fish.chu arowanasnakeskin arowana
