1. In order to improve the home environment, what kind of fish is better to raise at home? What are some good-looking small fish that are must-haves to raise at home?

With the economic conditions getting better and better, people have more things to do besides their normal life, work and study. As long as they have the conditions, they like to raise some flowers, plants and pets at home to cultivate their sentiments. Today, let's talk about what kind of fish is suitable for home. The fish raised at home are not only for beauty, but also for whether they are easy to raise and whether they are gentle. Let's take a look at five kinds of fish suitable for home raising.

Koi

Koi is one of the most popular high-end ornamental fish in the world. Koi lovers have given it the title of "swimming artwork". Koi is an omnivorous fish with a strong ability to adapt to various living conditions. It does not have very high requirements for water quality and temperature and is gentle in nature.

Guppy

Its full name is Peacock Flower. It has a gentle temperament and can be raised together with some tropical fish. It is a very lively fish, giving people a feeling of youthful vitality.

Kissing fish

I believe everyone knows a little about kissing fish, and they seem to be a romantic fish. But in fact, they kiss to fight. Kissing fish are docile and lively, and are called the "cleaners" of fish tanks.

Moonfish

The moonfish is also small and exquisite, which is somewhat similar to the guppy. The color of its body is very bright, and people can't help but feel happy when they see it.

Mary Fish

Also called Molly fish. Molly fish are also gentle in nature, never attack other fish, and have strong adaptability to water temperature. They have high requirements for water quality and need to change water frequently. For domestic fish, you basically only need to consider whether it is easy to raise, whether it has strong adaptability, whether it is aggressive, and then it depends on your eye. If you think it looks good and you like it, you can take it home without hesitation.

Gilded Goldfish

The main characteristics of the gilt goldfish are its short and round body, normal eyeballs, pointed head, well-developed fins, a large four-part tail, and more than 4 forks in the tail fin. It is an ornamental fish. There are many varieties of gilt goldfish, with the most color variations. There are currently more than 50 varieties, most of which are best-selling varieties with a high international reputation.

Thai fighting fish

The Thai fighting fish, native to Thailand, is also known as the five-color fighting fish. Like other fighting fish species, it has a strong ability to adapt to the environment and has a gorgeous and exaggerated appearance. It is one of the easier ornamental fish to raise. Due to the aggressive nature of male Thai fighting fish, it was regarded as a tool for entertainment in many places a long time ago.

It is better to raise some ornamental fish at home, such as goldfish and Thai fish, which are better choices.

I think it is best to keep some easy-to-survive ornamental fish at home, which can improve the style of the living room. Chinese mullet, small mixed sea bream, anchovies, and goldfish are all very good choices.

It is best to raise goldfish or some crucian carp. I think you must change the water frequently when raising fish, otherwise they will die.

2. What kind of fish are suitable for raising in a family fish tank, and which fish are better to raise at home

Goldfish: Goldfish is a common wide-temperature fish with a long history of cultivation in my country. Arowana: Arowana is a large ornamental fish native to Southeast Asia. Guppy: Guppy is a very common small tropical fish with strong adaptability to the environment and easy to breed. Parrotfish: Parrotfish is an artificially cultivated ornamental fish with a relatively high demand for oxygen. Koi: Koi does not require high water quality and has a relatively diverse diet.

1. Goldfish Goldfish are a common wide-temperature fish with a long history of cultivation in my country. They are usually divided into four types, namely grass-type, culture-type, dragon-type and egg-type. Among them, grass-type goldfish is the most widely bred variety, which is not only beautiful in appearance but also easy to raise. Egg-type is a more popular variety in recent years, with a round and cute appearance.

2. Arowana Arowana is a large ornamental fish and an ancient primitive fish species. It is native to Southeast Asia and is already very rare in the wild, but there are many in captivity. As a tropical fish, it has certain requirements for water temperature, which should be kept above 24°C. In addition, during the breeding season, the male fish will hold the eggs in its mouth to protect them.

3. Guppy Guppy is a very common small tropical fish. There are many types of guppies with rich colors. No matter which type, they all have a beautiful big tail. It is worth mentioning that guppies are very easy to raise as ornamental fish. They have strong adaptability to the environment and are easy to breed. They are especially suitable for beginners to practice.

4. Parrot fish Parrot fish is an artificially cultivated ornamental fish, which is also quite popular at present, mainly because of its bright red color, so it is very popular in China. Due to the congenital defects of this fish, it has a high demand for oxygen and needs a high dissolved oxygen to survive. In addition, attention should be paid to feeding and water temperature to keep its body color bright.

5. Koi Koi, like goldfish, is a wide-temperature fish, but it is relatively large and requires a larger fish tank to keep it. However, it does not require high water quality and has a more diverse diet, so it is still very easy to keep.

3. What factors can cause changes in the body color of domestic ornamental fish?

Why, when the same ornamental fish is kept in different aquarium environments, their body color will change to a certain extent: some changes are subtle, while others are very obvious. And the state is not consistent. Why is this? What causes this phenomenon?

Several factors that affect the state and body color of ornamental fish -

1. Light brightness and ambient color.

Different light intensities and different environments will cause the body color of ornamental fish to change to a certain extent. This is actually the so-called "protective color" of ornamental fish. In other words, it is just a "camouflage uniform". This "camouflage uniform" can make them blend into the environment and not be easily discovered by prey or predators. We have also talked about the importance of mimicry in previous articles. Many ornamental fish follow mimicry. Take the most typical example - dead leaf fish, which often floats in the water. The pointed body and the color of dead leaves can easily make them be mistaken for dead leaves. This is protective color, which is also mimicry.

If the overall environment is brighter, the color of the ornamental fish will be lighter and less vivid; conversely, if the environment is darker, the color of the ornamental fish will be darker. This is actually one of the reasons why we often use black background paper. It is the instinct of ornamental fish to change color after arriving in a new environment.

2. Water quality and health status.

When the water quality is poor, the fish's body color will become lighter or have black stripes. The body color change when the water quality is poor is quite abnormal and looks very strange. In addition, the ornamental fish will not be as lively as usual and will not have a strong desire to grab food. This is a pathological condition. Poor water quality breeds all kinds of diseases.

When the water quality is good, if the ornamental fish suffers from enteritis, internal parasites and other diseases, the body color of the fish will become darker and the fish may lie on the tank.

3. Different genders.

We all know that in the world of ornamental fish, the most beautiful fish are usually males, while female fish do not have such gorgeous colors. The same fish, if they are of different genders, will actually have a big difference in color after they are colored. There is nothing to say about this, it is just a matter of physiological characteristics.

When faced with the situation where fish of the same species have different body colors in different tanks, do we need to take any measures?

First of all, you must make sure that if the fish is sick, you must take treatment measures. In addition to observing the color of the body surface, you must also judge the color based on other symptoms. Of course, sometimes the body color of the same fish is different, which is also related to the fact that they have just been put into the tank. In this case, you can refer to the previous article, which talks about how to make the newly bought fish quickly familiar with the environment and restore their body color.

There is nothing you can do to change the color of the fish due to gender issues, or you can change the fish. In addition to the above reasons, if the fish itself is healthy, you can make the color of the fish more vivid by landscaping and changing the environment. Most ornamental fish background papers are black, such as the brontosaurus, the Chinese croaker, and the Taidou. They all prefer a secluded environment. The black background can create an atmosphere, provide a sense of security, and further highlight the color of the fish.

Of course, some fish are not suitable for black backgrounds, it depends on what kind of fish you are raising. You can also change the water quality. Cichlids are most likely to grow in hard water, while fish from South and North America prefer acidic or neutral water.

In most cases, the body color of the same species of fish in different tanks will change due to different environments, water quality, and temperature. This is normal.

Generally, the first reason is that the fish was frightened, and it would not change color at the time, but it would change color easily after it was brought home. Another reason is that you bought a fake fish, the color was painted on, and then you kept it in the tank for a long time, and the color changed.

The fish may be frightened or sick, which may cause their body color to change. So pay attention to the fish's dynamics in time.

Generally, after a period of time, the color of goldfish will become lighter, even in greenhouses with poor light. This is mainly caused by insufficient sunlight, insufficient nutrition in bait, poor water quality, lack of oxygen and disease, etc., which can also cause the color of domestic goldfish to become lighter.
