Why do you entangle lights when raising dragons?

Compared with other ornamental fish, the arowana has large scales, and when exposed to light, it reflects brilliance and colors that other tropical fish do not have, and the importance of hair color is self-evident.

Arowana (take the red system as an example) color principle:

The pigment cells (chromogenic cells) in the dermis under the scales and the guanosine on the outermost surface play a major role in the hair color of arowana. A variety of cells are scattered in the dermis, which can stretch with the intensity of light and changes in the environment. Various pigment cells have the function of absorbing and reflecting light wavelengths. Therefore, in different lighting conditions, arowana will show a variety of different colors.

Many fish friends will ask the arowana how much hair color?

In fact, there is not an accurate time, generally in the dragon fish body length of about 25 centimeters, there will be signs of hair color. Of course, the most important determinant of arowana hair color is pedigree.

However, the effect of environment on the hair color of arowana can not be ignored. The dragon fish is an out-and-out "chameleon". Whether it is the golden dragon or the red dragon, the color effect will get twice the result with half the effort after turning on the lights, and the appreciation will be greatly improved. Many people practice that the stronger the light, the more lasting the arowana color speed will be, long-term exposure to arowana scales, the frame appears faster, the Gill cover color area will gradually increase, under the conditions of environmental permission, the arowana color will also be deepened.

Why are arowana farmers entangled with lights?

1. Reasonable lighting can promote the hair color of arowana.

The hair color of arowana needs enough light, this light is not whitewash, is the effective output of ultraviolet light, light irradiation can stimulate the production and accumulation of the pigment layer, promote the growth and color of fish, of course, the premise is that it must have enough bloodline as a guarantee.

two。 High-quality lighting and correct placement can prevent arowana from losing eyes and uneven hair color.

Whether the penetration of the arowana lantern is strong, whether the luminous area is large, and whether the distribution is uniform is very important. Excessive light will stimulate the arowana to lose its eyes, you can imagine looking directly at the sun at noon, the soft color band is very important for the light!

If the light is too strong, it will lose your eyes, and the incorrect position of the lights will also cause you to lose your eyes. The simple use of underwater lights will cause excessive side lighting, and the common problem is to swim sideways first and then lose eyes; sometimes we do not use underwater lights and arowana also lose eyes on both sides, which is often caused by too strong top lights. The water lamp had better be used with the overhead light to ensure the homogeneity of the lighting environment inside the fish tank and avoid the occurrence of eye loss.

If the position of the lamp is not properly placed, it will also cause the arowana to be dark on one side and shallow on the other. Usually, a water lamp can be arranged on both sides of the fish tank to solve this problem.

3. Safe use of electricity

Fish tank lamp involves electricity and water, the safety of electricity is very important!

Need to ensure that the dragon fish lamp materials are reliable, overvoltage protection, current unstable protection, to prevent poor contact damage; lamp high sealing design, amphibious, waterproof and leakage; high temperature, anti-collision, reduce lamp body heat; plug and wire standards; waterproof protective cover.

The high temperature of the lamp tube will seriously test the quality of the lamp tube. Once the leakage occurs in the fish tank, in addition to the threat to the whole tank of fish, the safety of household electricity will also be affected! It is very important to ensure that the lamp tube continues to glow steadily, prolong its service life, and is safe and reliable.

4. Other

For example, the sucker of the lamp tube is powerful and effective, which can ensure that the lamp tube is placed in any position without falling off; because the fish tank lamp tube is used for a long time, it is necessary to ensure its high efficiency, energy saving, low carbon and environmental protection.

If you want to distinguish whether the light is good or bad, you can turn on the cell phone camera and look at the fish tank to see if the light in the fish tank has a splash screen.

How long should the dragon fish light shine?

It is best to be close to nature and distinguish between day and night. If you want to pursue the color speed, you can slightly increase the light time and intensity, but not too strong, so that the fish have to adapt to the process, the ecological clock does not have to change too much. If the arowana gets a good hair color by strengthening the light source for a long time, it will decline after a long time, which is the same as the golden dragon roasting color, and everything need not be too far-fetched.

Of course, feeding, water quality and other factors are also closely related to the hair color of arowana. Hope that the majority of fish friends can make reasonable use of every aspect of the details, and finally their own fish are to achieve their most satisfactory hair color. However, the effect of good lighting on arowana is visible to the naked eye!
