Its body is long and bearded, resembling a dragon, so it is a very popular fish among the Chinese. Arowana has a strong character and feeds on small fish, frogs and insects. The water temperature for its survival needs to be high, and it needs to be maintained at 27-28°C during growth. The broodstock will hold the eggs in its mouth for hatching.
1. Pearl Dragon
Pearl dragon
Pearl dragon is also called Australian dragon. Pearl dragon is native to Australia, 24～29℃, pH6.5～7.5. This species is very healthy, with a small and elongated body, 50 to 60 cm long. There are red freckles on the center of the scales, caudal fin, dorsal fin, and ventral fin. Some scale frames have red edges. There are 35 scales on the lateral line and anal fin pedicles. There are 31 branches, and the caudal fin pedicle has 21 branches. The beards are short and small, and they are aggressive by nature, which often causes the beards to break.
The egg diameter is about 1 cm, and 50 to 200 eggs are often laid. The body is light brown, the dragon's whiskers are black and soft and short; the juvenile fish shows a silvery white color, the back is copper brown, and the back is somewhat bent; when the adult fish has obvious red spray spots on the tail, the scales are light blue. Light red ring pattern. If the fish is fed reddened bait from a young age, there will be red freckles on the tail fin. This type of arowana has a slightly fierce nature., when hungry, they will look for fish to eat, including larger fish.
2. Qinglong
Qinglong
When the Qinglong fish is in its juvenile stage, its intrinsic color type and unique dark markings will appear. Currently on the scales, as the pattern grows, it will appear in a U-shape or horseshoe shape on the scales. The spotted fish has a little bit of cyan color. When it becomes an adult fish, the golden metallic luster will not appear on the scale frame. The scales are silver with some gray and green. The luster is not bright, and most of them are off-white.The fins of the juvenile fish are slightly yellow, similar to the golden dragon. Compared with the blood red dragon from Indonesia, the body height is shorter. The body shape is similar to the over-backed golden dragon from Malaysia. The head of the adult fish is smaller than other Asian dragon fish. On the small side.
When they grow up, they will turn blue-green and gray. If you want to distinguish them easily, the head will be shorter and smaller. The chin is dull and lackluster.The body shape is shorter than other arowanas. The number of scales on the lateral line, the number of dorsal and anal fins, and the number of vertebrae are the same as those of other Asian arowanas. The water quality is the same as other Asian arowanas, and the nature is the same as other Asian arowanas. It is difficult for two fish to coexist peacefully in an environment with insufficient space.
Three. Cross-back Golden Dragon
The body of the fish is similar to that of the red-tailed golden dragon, But the golden scales are more beautiful than the back. There is little natural growth, and the price of some good-quality ones is only lower than that of the red dragon, and different varieties are even the same price as the red dragon. When the cross-backed golden dragon is young, it is characterized by blue with a green background and light red with a golden thin frame inside the dots. After growing up, the shallow scale frame will turn into golden yellow, and the golden-yellow blue or green scale bars will reach the fifth row of scales. , better than all tea leavesThe color of the back, the upper part of the back and the tail fin should be dark blue, and the other fins should be golden red. The feeding method is the same as that of all arowanas. The over-backed golden dragon is slimmer than the red dragon. If the water quality changes slightly, it will easily suffer from skin diseases. Moreover, the edges of the fish scales will be corroded and become jagged, making the pattern difficult to see.
4. South American Pterosaurus
South American Pterosaurus, also known as Paiguosaurus, is named because the lines on its sides resemble ribs. This species gives people the impression that it has a disgusting face, so it must eat fish. However, the South American Pteranodon is not as ferocious as imagined. If it eats fish, it may only be able to eat fast-moving fish, usually eating red worms or bottoms. Fish feed is all that is needed. There is no need to give it special fish to eat. It may starve to death without eating a single fish. The regional differences among co-species are very strong, so we should pay great attention to this.It can be inferred that the tail fin of the similar species Indian Pterosaurus is longer.
5. Nano Qinglong
< p>Because the regional lakes are close to the small town of Nami, when locals want to hunt fish, they will expect Nami's relationship. , hence the name. Essentially this lake is part of the Muda Reservoir. When it was young, this fish didn't have any special characteristics, no special markings or shiny gills, etc. In the first year of feeding, they will have a good appetite and grow rapidly. When they grow up, their gills and scales begin to have snake-like patterns, their eyes turn red, and their pectoral fins have shiny freckles. Now they have been bred in captivity, and they believe that based on their breeding techniques, they can be successfully promoted and bred artificially.
