Arowana can be divided into the best Several categories, let’s take the dried red-tailed golden dragon as an example. When the red-tailed golden dragon is 7 to 8 centimeters in length, all the fins are yellow. Only when the fish’s staple food is shrimps rich in red pigment, the fins will be red. It will appear when it reaches 10 to 12 centimeters in length. By the time it is 15 to 20 centimeters long, the golden edges of the scales have also appeared. This kind of gold-edged scales will always "climb" up to the fourth row. So do all varieties of arowana have any unique characteristics?
1. Chili red
Background color: The first one is that the background color of the scales is blue; the second one is that the head has green fish skin.
The background color transformation process: slowly first changes from yellow to orange, then from orange to light red, and finally to dark red.
Background color conversion time: The best time is more than one and a half years, generally four years or more.
External characteristics:
1: Dark red thick-framed scales 2: Dark red gill cover 3: Larger fins and tail fin (young fish have a wider body, larger eyes, and a diamond-shaped tail fin , pointed and over the head, and red fins, especially easily identified from its pectoral fins. The diameter of its large eyes is often equal to the distance between the eyes and the tip of the mouth. The scales are tinted with light green and yellow or orange. )
2. Blood Red Dragon
Background color transformation time: The color will be revealed soon after one year
External characteristics: 1: Thin-framed scales 2: Gill cover is Red 3: The figure is thinner and longer than that of chili red. (The juvenile fish is relatively long, and the fins and eyes are relatively small. The fins are also red, but the difference is that its tail fin is round, the head is no longer than the pepper red dragon juvenile, and the scales are slightly shallower. Green and pink colors. )
3. Orange-red dragon
External characteristics: The orange-red dragon is relatively longer than the blood-red dragon, and can generally grow up to 90 centimeters. The arowana’s eyes are larger than those of peppers. Red dragons are small, with orange-red gill covers and often no more than orange scales. Some orange-red dragons have orange-red fins, and some inferior orange-red dragons even have yellow fins. The color on the scales is dull (the head of the young fish is relatively round.)
4. Red Tail Gold
External characteristics: 1: The fifth on the back of the fish bodyThe entire second row of scales and the sixth row are all very special black or dark green, and include the dorsal fin and the upper third of the caudal fin.
2: The scale frame is shining golden yellow. The golden color of the best red-tailed golden dragon will even reach 1/2 of the scales, but the golden color on the scales can only reach the fourth row at most.
3: The gill cover part is not red, but is completely bright golden yellow. 4: The upper third of the caudal fin and the dorsal fin are dark green, and the lower two thirds of the caudal fin are dark green. Partly, the anal fin, pelvic fin and pectoral fin are generally orange-red. This aspect is quite similar to the red dragon.
5: The red-tailed golden dragon is more aggressive than the red dragon, but it is definitely more docile than the over-backed golden dragon.
6: Background color: blue, gold and green.
When the red-tailed golden dragon is 7 to 8 centimeters long, all the fins are yellow. Only when the fish’s staple food is shrimp rich in beta-carotene, the red fins will appear on it. It grows to a length of 10 to 12 centimeters. By the time it is 15 to 20 centimeters long, the golden edges of the scales have also appeared. This kind of gold-edged scales will always "climb" up to the fourth row.
5. Over-back gold
Similar to the red-tailed golden dragon, the most essential difference is that its golden scales can surpass the tea-green back to make the whole body appear golden.
