Beautiful Arowana

The color of Arowana is very bright, such as red Arowana and Arowana (definitely introduced), you can see their dazzling brilliance after developing color, which is a beautiful scenery among the fishes. However, some people will always encounter the situation of Arowana not developing color, or The complexion is dull, so what are the methods to make the hair color of the arowana or what factors determine the hair color of the arowana?

1. Several stages of arowana hair color

Arowana The color of fish generally changes color in stages, usually starting from the gill cover, and then to other parts. It developed slowly in this way, and by the time it reached adulthood, the arowana's mood completely calmed down. At this stage, we can use some methods to control the hair color of the arowana so that it has a more perfect expression.

The first stage: cheek hair color

6 months old For young dragons, the gills begin to develop color when the body length is about 25 centimeters. The initial hair color converges around the lines of the cheekbones. At this time, if the color can appear orange-red or pink, it can be said to be very ideal. The thicker, deeper, and thicker the color, the better. The size of the hair color area does not matter, what matters is the color quality and form of the hair color. There are also outstanding little dragons that will develop color when they are younger. This is related to the nature of the arowana itself and also to the breeding of attractive colors. The hair color on the cheekbones will continue to last.

The second stage: the first scale hair color

In Soon after the baby dragon's gills develop color, and when the body length reaches about 30 cm, the scales begin to develop color. Initially, the first scale frame of the scales on the front half of the body starts to develop color, usually in the 2-4 rows, and rarely in the 5th row, but this does not rule out the possibility.

The third stage: hair color of the second scale frame

After the hair color in the previous stage reaches a certain level, the expression of hair color will tend to be stable, making people feel that the hair color has stopped. Generally, after raising the arowana for more than a year, when the arowana is about 35-40cm, the color area of ​​the gill cover begins to increase, the redness of the color of the first scale frame becomes richer, and the second scale color of the front half of the body begins to increase. The frame begins to develop color, which is the most critical moment. As the hair color develops, the second scale frame begins to deepen significantly.

The fourth stage: Exaggeration and deepening of hair color area

When the arowana body grows to more than 50cm, the hair color will develop in stages: the area increases, the color deepens and thickens, and the scales begin to mix. This stage will last for eternity. It can be said that the hair color of red dragons is endless, and as the age increases, the changes in body color will continue for a long time. As the arowana grows, it will take 5 to 8 years for its body color to be basically stable, but then it will change slightly as time goes by. The hair color process of Arowana is a wave-shaped process. Especially for the first color hair method, dispersion often occurs. The so-called dispersion means that the area of ​​hair color increases, which brings about a decrease in both the visual effect and the actual redness. Therefore, there will be a wave-shaped hair color process, and hair color will often appear. The wonderful process of area increase – fading – occurs, and this process is repeated many times until the bright red arowana grows.

Two factors that influence the hair color of Arowana

1. Water quality

Maintaining good water quality is a well-known aspect for aquarists. It is generally recommended to change the water frequently. , but it is different if it is a medicinal bathtub. Frequently change 1/3~1/5 of the water a week (depending on the possible penetration of the fish in the tank), and try to avoid large water changes. Remaining bait must also be removed to avoid water quality reversal. . Generally speaking, weakly acidic soft water is better. Soft water can be cultivated by mountain spring water, RO water or soft water tree materials, etc.; while sulfuric acid can be cultivated by adding black water, grass mud pills, or Amazon soil, etc.

Red Arowana

2. Situation

Situation again Including moving vats, dispensing medicine, scenery, etc. It turns out that it is a situation where the fish fade due to changes in the environment. It should be understood that the body pigment of the arowana is just attached to the fish scales, so all circumstances will affect the body color expression of the arowana. In terms of backgrounds, red dragons are mostly matched with black, red, or blue. Golden dragons are mainly blue or black. It depends on the color of the arowana.

3. Lighting

Red Dragon proposes to use weak optical activity It is better to use plant lights to illuminate. The golden dragon mainly uses blue lights with white lights. In fact, whether it is a plant lamp or a sun lamp, weak optical rotation is better when choosing light, because if it is irradiated with too strong light, the body color of the arowana will become lighter. The color system of the lamp should be based on the background color and future color of the arowana.
Feed, I won’t introduce much about feed. Another thing to mention is that it is said that it is easier to achieve the purpose of inducing color by lowering the water in the tank to about 10 to 15 centimeters. This can prevent eye loss and reduce the water pressure; this method is a dry method in the growth field. , but the effect is a matter of opinion.

3. Methods for Arowana Hair Color

1. Change the color

Change the color of the light. This method is similar to the method used on the red dragon. It can make the color of the over-back golden dragon appear. Some level of change. First of all, it is best to go to an electrical appliance store to choose the lamp you want to use. Natural aquariums may sell several kinds of lamps, and that is okay. If you want to emphasize the color of gold, the lamp you need to choose is not a bright white type with high color temperature, but a low color temperature solar tube that is close to yellowish, so as to bring out a more conspicuous golden color

< p style="text-indent:2em">2. Light background

The arowanas in the gold series and red series are not only beautiful in appearance. However, even the breeding methods are not universal. For example, while red dragons should be kept in black aquariums, it is recommended that over-back golden dragons be kept in clean light-colored aquariums. Why do you say this? It’s because the charm of the cross-backed golden dragon lies in its dazzling metallic light.Color, and the stronger the metal reflectivity of the scales, the higher the price evaluation. In order to represent its charm, an aquarium with a light-colored background may allow the light to be fully reflected in the aquarium; in this way, no matter where the golden dragon swims, the scales can receive light. It will become more dazzling as it rises.
