Why are the fish in the tank getting lighter in color?

The pale and tarnishing of the fish is affected by the water quality or even the lack of oxygen.

In fact, the turbidity of the water in the fish tank mainly includes three types of turbidity, such as physical turbidity, chemical turbidity, biological turbidity, and the solution of different properties of water turbidity is also different.

1. Physical turbidity: that is, we can all see the floating particles with the naked eye, in professional terms, the turbidity of the water body caused by too many particulate impurities in the tank is called physical turbidity, the color of the water is whitish, and the granular things can be clearly seen. Generally, it is the most common in the early stage of cylinder opening, mainly because the new filter material is used in the early stage, and a large number of particulate impurities and foreign substances such as short fibers will cause turbidity in the water body.

However, this kind of turbidity is not terrible, as long as it can be solved by putting in fine cotton or shrinking the filter hole.

2. Chemical turbidity: This refers to the turbidity of water quality caused by chemical reagents (mainly medicines) and water purifiers, such as potassium permanganate. The color is purple, and if it is missing, it is pink.

Such turbidity can be solved by activated carbon adsorption, so novices should not apply drugs casually when raising fish, which is not good for water quality and fish.

3. Biological turbidity: This is mainly due to the mixing caused by the proliferation of microorganisms, which is generally manifested as the water in the fish tank is chaotic and unclear, giving people a hazy feeling, which is the most common turbidity, and such turbidity needs to understand the cause in order to find an effective solution.

a. Turbidity caused by green algae: This is caused by direct sunlight (sunlight), and the color of the water body is greenish. When encountering such turbidity, the easiest solution is to avoid sunbathing.

b. Turbidity caused by the proliferation of bacteria: This is caused by the weak filtration system, which causes the accumulation of fish feces residues and triggers the proliferation of heterogeneous bacteria, resulting in mixed water. At this time, we can install a reasonable matching filtration system to strengthen the flow in the tank, so that the fish can be filtered out in a very short time after being generated, and the residual bait can be fished out in time, so as to ensure that the water quality will not be turbid.

Another solution is to install UV germicidal lamps. (It should be noted that the germicidal lamp should be installed in a hidden place, and should not attract fish and solid surfaces where nitrifying bacteria are cultivated).

c. The death of nitrifying bacteria will cause other flora to grow rapidly, resulting in turbidity of water. To solve this turbidity, we must first strengthen the nitrification system and add nitrifying bacteria to solve it, so as to maintain water quality.

Therefore, if we want to make the water in the fish tank clear, it is necessary to strengthen physical filtration, efficient filtration of organic matter such as fish feces residues is the key, and more importantly, to establish a perfect nitrification system, and the reasonable use of UV ultraviolet germicidal lamp + EM bacteria tablets can quickly solve the problem of turbidity, so as to maintain the health of the water body.

The main problem is water, raising ornamental fish is generally an urban family, and the city is tap water, you know how much chemical damage is contained in tap water, followed by the problem of bait, I once raised a tropical fish macaw fish, only to buy back the color is very beautiful, it didn't take long for the color to begin to fade to light red. Later, after being instructed, the newly bought ones began to feed fresh feed, which was much better, such as red worms, but it didn't change at all, as if it was impossible. It might be better to solve the water problem.

If you give the fish low-quality fish food for a long time, the color of the fish will definitely become lighter! The reason is that cheap fish food is cheap, and it will definitely not have any nutrition, you get what you pay for, don't think that you can buy something for 100 yuan for 10 yuan! The nutrition of fish can't keep up, and the body is in a sub-healthy state!

Color is a sign of fish health! Just like the bronzer we're after**! Healthy performance!

If a person is chronically malnourished, you can surely tell at a glance that there is something wrong with him! For example: the little radish head in a primary school text!

So if you want the fish to have a good hair color! You've got to at least give it something to eat.

The line should be suitable, the fish also need light, there is no daylight, use the light to supplement, but can not be exposed to strong sunlight, to use curtains, otherwise the green algae is generated quickly, the water for fish farming is a faint light green, green algae is seriously not suitable for fish farming.

A matter of light! Fish are exposed to sunlight for a long time! It will be easier to get lighter and lighter! Small fish also need to be in the sun a lot!

The health of the fish is also the key, fish farmers can distinguish the health of the fish through the change of fish color, unhealthy fish usually become very light in color, and then the male fish are usually brighter in color, and the female fish are worse.

The color of the fish tank is a problem! If the fish tank is white! Then you'd better swap it out! I change it to a tank with the color! Its color will be better!

It is also said that fish farming starts with water! If the water is not good, the fish will turn white! If you don't keep the water well, the fish will get sick if you live in it for a long time! Of course! Sick fish will also fade and turn white.

Sunlight is needed by 99 percent of all living beings on Earth! I'll give you an example: if a person doesn't see the sun for a long time, he will appear very white, the kind that is miserable! Looks unhealthy! The same goes for the fish, if they don't see the sun for a long time, they will also turn white!

It has a close relationship with light, water quality, and containers. There are generally three reasons for the gradual lightening of its color:

1. Keep it indoors for a long time and don't see sunlight. If you move the fish outside and see the sun, the color will gradually become vivid again after more than 20 days.

2. Fish farming in white water. Always changing the water to a clean (i.e., colorless and transparent white water) can also cause the fish to gradually lighten in color. It is best to feed with tender green water.

3. If you feed in a white container (such as a white porcelain basin, etc.), the color of the fish will also become lighter. If the fish are fed in a clay jar filled with strong green water for a few days, the color of the fish will become vibrant.

To make tropical fish.

To restore vivid colors, you can try the above methods.

1. Leave tap water in the sun for a few days, and some green algae will be produced in the water.

Second, the water for raising goldfish should not be changed completely often, and only one-third of the water should be changed each time;

3. Suck out the sediment at the bottom of the fish tank every day, and then inject the same amount of new water

The above methods will slowly turn the water green, becoming tender green water or strong green water.

Q: Whether my "map" is newly bought or kept for a period of time, as long as it is in my house for a day or so, the black part will fade and gray. Is it a light or water quality issue?

A: It has a close relationship with light, water quality, and containers. There are generally three reasons for the gradual lightening of its color:

1. Keep it indoors for a long time and don't see sunlight. If you move the fish outside and see the sun, the color will gradually become vivid again after more than 20 days. 2. Fish farming in white water.

Always changing the water to a clean (i.e., colorless and transparent white water) can also cause the fish to gradually lighten in color. It is best to feed with tender green water. 3. If you feed in a white container (such as a white porcelain basin, etc.), the color of the fish will also become lighter.

If the fish are fed in a clay jar filled with strong green water for a few days, the color of the fish will become vibrant. To restore the vivid color of tropical fish, you can try the above methods. Whether you are raising goldfish or tropical fish, it is best to raise them in tender green water.

Fish are raised in tender green water, with fewer fish diseases and fresh colors. Here's how to make feed water green: 1. Leave tap water in the sun for a few days, and some green algae will be produced in the water; Second, the water for raising goldfish should not be changed completely often, and only one-third of the water should be changed each time; 3. Suck out the sediment at the bottom of the fish tank every day, and then inject the same amount of new water

The above methods will slowly turn the water green, becoming tender green water or strong green water.

This is usually due to two reasons: a sudden change in water temperature and pH. To put it bluntly, it's a stress response!

There are three common stress responses in ornamental fish: lying on the tank, body surface congestion, and blindfolding.

In fact, there are three uncommon stress reactions, and the more common one is fading.

Another situation is that some special ornamental fish species, because at the time of sale, another situation is that some special ornamental fish species, because at the time of sale, in order for them to have a better appearance, and eat some special feed, and even play hormones. In this way, these ornamental fish can have a better ornamental experience in a short period of time. The most common is red parrot fish, and some red parrot fish are actually fed special red-increasing feed, or even hormones.

At this time, they are very good-looking in the aquarium, but after returning home, after raising ordinary feed for a period of time, their color will slowly fade and turn pink in order for them to have a better appearance, and eat some special feed, and even take hormones. In this way, these ornamental fish can have a better ornamental experience in a short period of time. The most common is red parrot fish, and some red parrot fish are actually fed special red-increasing feed, or even hormones.

At this time, they are very beautiful in the aquarium store, but after returning home, they will slowly fade and turn pink after raising ordinary feed for a period of time.

There are also relatively rare ones that are caused by gene expression, which is rarely the case.

If it is a flamindivian parrot, it needs to be fed with color-enhancing feed for a long time, otherwise the color will slowly fade.

Some fish have no color, which means that they have just entered the tank and are not very suitable for the water quality, and there will be changes.

There are also some colors that are laser-hitting, and this one will fall.

The head is hypoxic, and the dissolved oxygen in water is low.

Less than 5 milligrams per liter of water will float your head.

If it's any lower, the fish will die.

Plus you put on the balcony.

Can this kind of day not be hot?

For more hypoxic solutions, add an aerator for more than 10 yuan.

Replace it with fresh sun-dried water.

It is related to the quality of light and water.

Everything grows on the sun.

The main reason is that there is too little light and poor growth, so the color gradually degrades, which is more dangerous. The position of the fish tank should be changed to half yin and half yang, so as to ensure the required light and healthy growth.

Secondly, there may be a short-term change in the color of the new water, and then it becomes very light, which is a problem in feeding. In breeding, in order to keep the goldfish bright, it is necessary to pay attention to the density of fish in the fish tank should not be too large, and the number should be less than more.

The amount of water exchange should be increased appropriately, try to use the residual bait and precipitate every day to supplement some new water, once a week to change the water 1 3 1 4, but a water change can not be too much, tap water should be dried for 1 2 days, on the one hand, the water temperature is similar to the tank water, on the other hand, it is also for the sheng huai hui to remove the chlorine in the water, and the chlorine will also make the color of the fish lighter.

Summary. The pale color of the fish in the fish pond can be caused by the following reasons:1

Insufficient or unbalanced feed: The color of the fish is related to the feed, if the feed is insufficient or unbalanced, it will affect the synthesis of pigment in the fish's body, resulting in a lighter color of the fish. 2.

Water quality problems: Poor water quality will also affect the color of the fish, such as too high or too low water temperature, insufficient oxygen in the water, toxic substances in the water, etc., which will affect the metabolism and pigment synthesis in the fish, resulting in the color of the fish becoming lighter. 3.

Disease problems: Some diseases can also cause the color of fish to become lighter, such as bacterial infection, parasitic infection, etc., these diseases will affect the immunity and appetite of fish, resulting in the metabolism and pigment synthesis in the fish body being affected. In response to the above problems, the following measures can be taken:

1.Reasonable feeding: Provide balanced feed to the fish to ensure the nutritional needs of the fish and avoid the problem of insufficient or unbalanced feed.

2.Strengthen water quality management: ensure that water quality is clean and transparent, control water temperature and water quality, increase oxygen content in water, and avoid the production of toxic substances in water.

3.Disease prevention: strengthen the management of fish breeding, keep the fish pond environment clean and hygienic, timely detect and improve diseases, and avoid the occurrence and spread of diseases.

Hello friends. What's wrong with the fading color of the fish in the fish pond.

The pale color of the fish in the fish pond can be caused by the following reasons:1Insufficient or unbalanced feed:

The color of the fish is related to the feed, if the feed is insufficient or unbalanced, it will definitely affect the synthesis of pigment in the fish, resulting in the color of the fish becoming lighter. 2.Water Quality Issues:

Poor water quality will also affect the color of the fish, such as too high or too low water temperature, insufficient oxygen in the water, toxic substances in the water, etc., will affect the metabolism and pigment synthesis in the fish, resulting in the color of the fish becoming lighter. 3.Disease Issues:

Some diseases can also cause the color of fish to become lighter, such as bacterial infection, parasitic infection, etc., these diseases will affect the immunity and appetite of fish, resulting in the metabolism and pigment synthesis in the fish body being affected. In view of the above problems, the following measures can be taken:1

Reasonable feeding: Provide balanced feed to the fish to ensure the nutritional needs of the fish and avoid the problem of insufficient or unbalanced feed. 2.

Strengthen water quality management: ensure that water quality is clean and transparent, control water temperature and water quality, increase oxygen content in water, and avoid the production of toxic substances in water. 3.
