8 years of experience in breeding cold and tropical fish, give some suggestions to beginners

Although there is no big harvest, but also accumulated some small experience, here to exchange with you, novice reference, expert advice.

Fish farming is just water and fish. Water raises fish, fish also raises water, fish without water is dead fish, water without fish is stagnant water. So let's start with water and fish.

Water: people who raise fish all know that fish raise water first. Water is the living environment of fish, but not all kinds of water can raise fish. Some newcomers who have just raised fish often fall into such a misunderstanding on the issue of water: they think that as long as the water is clear to the naked eye, they can raise fish. In fact, it is wrong, the living environment of fish is very special and complex. Water temperature, pH of water, softness and hardness of water, mineral content, trace element content, beneficial microflora and so on. These play a vital role in the growth and survival of fish. Therefore, it is necessary to fully understand water in order to raise fish well.

Fish: because most of the fish we raise now are species that have been cultivated, improved and propagated for a long time, because of different species, different areas of cultivation, and different water quality, it also determines the different requirements of fish for water. Not all fish can be raised with the same water and the same method, for good fish cannot be raised that way.

The following is a rough summary of some personal experiences from several aspects.

1. Fish tank

To choose a fish tank, you should first choose according to the size of the home space, the color of the furniture and the style of decoration. If the choice is improper, it will appear to be out of harmony with the home environment, reducing the ornamental effect. Secondly, we should choose the size and depth of the fish tank according to the requirements of the fish. Large, dynamic fish should choose a relatively large fish tank, while small, quiet fish are the opposite. Of course, fish farming in grass tanks is a different matter.

2. Filtration circulatory system

Now there are many kinds of filtration, including internal filtration, upper filtration, side filtration, back filtration, bottom filtration, external filtration, and plant filtration mentioned by individual fish friends. However, no matter what kind of filtration, in addition to beauty, the most important purpose is to maintain a good water quality, so that the water can be rich in oxygen, minerals, various trace elements and beneficial bacteria, and maintain the acid-base balance and softness and hardness of the water. break down other harmful substances to fish. So choose the appropriate filtration circulatory system according to your tank and fish. To really achieve the purpose of filtering and circulation. In addition, the filter material should also be selected according to different species of fish. Generally speaking, the filtration system for raising tropical fish is usually composed of physical filtration (filter cotton), biological filtration (biochemical cotton, ceramic ring, etc.), chemical filtration (activated carbon, Maifan stone, etc.).

3. Water

Well water is mostly used in rural fish culture, which is rich in minerals, trace elements and toxic substances, so it can be used without special treatment (but pay attention to acidity and alkalinity, there are great differences between regions). Tap water is often used in cities, because tap water contains more chlorine, and chlorine is very harmful to fish, so it is necessary to burst before use (that is, adding oxygen with an oxygenation pump). The purpose is to remove the chlorine from the water as much as possible. You can also use open containers to trap water for the same reason. Personal experience, anger is generally 24 hours, naturally trapped in the water takes 3 days to a week or so. Trapped water into the tank (usually disinfect the fish tank with potassium permanganate), heating, filtration, such as raising high-grade fish, but also need a process to break into the tank, that is, to raise some low-grade and healthy small fish in the new tank, the aim is to let the normal metabolism of these fish establish a good biochemical environment in the water. So breaking into the tank is actually raising water. When the water quality is good, you can put in your favorite fish.

4. Fish

To choose adult fish, they generally choose healthy individuals with bright colors, gorgeous designs, strong appetite for food, lively and active, and afraid of people. It is also important to observe whether the fish feces are normal and whether there is any phenomenon of white stool and defecation. There is no phenomenon of rubbing the tank when the fish is lively, and so on. Choose young fish with moderate size, well-proportioned parts of the body, lively and active, and so on. Many fish friends have a lot of experience in this area, so I won't say any more.
