CATDOLL : CATDOLL: How to raise tropical fish?

There are many varieties of tropical fish, and the main breeding methods are:

1. Water

1. Water quality Artificial breeding of tropical fish requires soft water or low hardness water, and the pH is preferably weakly acidic or neutral. If the acidity is too strong, tropical fish will have difficulty breathing and grow slowly; if the alkalinity is too strong, the gill tissue of tropical fish will be corroded.

2. Change the water

(1) Partial water change. This means using a straw to suck out the feces, leftover bait and other dirt at the bottom of the fish tank. The amount of water sucked out should be 1/4 of the water in the tank. Then, add the same amount of fresh water at the same temperature that has been air-dried or chemically dechlorinated. The frequency of water change should be twice a week in autumn and winter, and three times a week in spring and summer.

(2) Replace all water. All equipment in the fish tank should be removed, and the aquatic plants and fish should be fished out and placed in another container with the same temperature as the original water. Use a sponge to clean the tank walls and bottom. Change the water once every 2 to 3 months.

2. Water temperature

Tropical fish are extremely sensitive to temperature and will soon die if the temperature is not suitable. The water temperature for most tropical fish is preferably 20℃～24℃, and the water temperature during the breeding season is preferably 25℃～28℃. The temperature difference between day and night should not exceed 4℃.

3. Oxygen

A certain amount of water plants should be planted in the fish tank, because aquatic plants produce oxygen during photosynthesis, which increases the oxygen content in the water. At the same time, timely removal of dirt and frequent water changes can also increase the dissolved oxygen in the water.

4. Lighting

If you place the fish tank in a room with sunlight, it is best to expose it to sunlight for about 1 hour each in the morning and evening when the sunlight is insufficient; if you place the fish tank in a room without sunlight, you should use light to illuminate the water plants, using a 60-watt incandescent bulb or a 40-watt fluorescent lamp for 6 hours a day. Light can make tropical fish grow faster and make the fish more colorful.

5. Free Range

The stocking density of tropical fish in a tank depends on the size of the tank. For first-time fish keepers, the lower the density, the better, and an air pump is needed. For the combination of fish in the same tank, quiet fish cannot be kept together with aggressive fish; large fish cannot be kept together with small fish. There are many choices of tropical fish feed, such as fish worms, bloodworms or packaged feed suitable for different types of tropical fish. Raw bait and live bait must be cleaned to control the source of disease.

The water for tropical fish should be kept like this:

1. First, you need a pump and filter cotton. After a period of time, various impurities in the water will be filtered out. The pump must be turned on 24 hours a day.

2. Put some nitrifying bacteria in the water. There are such medicines sold. In fact, this is a kind of bacteria that evolves water quality. Don't think it is the kind of bacteria that causes viruses.

3. Grow some easy-to-grow aquatic plants in the water, such as water fig, centipede grass, etc. Don't buy too small floating aquatic plants. If these die, it will be difficult for you to clean the tank. You can put some liquid fertilizer at ordinary times, or it is better to have bottom fertilizer under your sand from the beginning. If there is no problem with the aquatic plants, you can raise fish. When raising aquatic plants, pay attention to the light. My experience is that the light must be strong. Don't turn on the light all day without strong light. It's not good. Don't regret it. 8-10 hours a day is enough.

4. Wait for 3 months, some say 1 week. In short, you can raise some easy-to-raise fish at the beginning, such as tiger skin, Congo or flag fish, and add one or two scavenger fish. If there are water plants, don't raise goldfish, because goldfish will eat the water plants.

1. Filter, heat, light. I don't know if your filter comes with wave-making and oxygenation? It's best to use oil oxygenation.

2. First, let’s look at the aquarium. The following is what I posted on my blog before.

After buying a new tank, you need to install various equipment, such as aquatic plants, bottom sand, circulation devices, lights, automatic temperature control devices, etc.

Then fill the tank with water and add the "nitrifying bacteria" purchased from the store. Start all the devices and let them work for more than 48 hours. At this time, the water environment in the tank has become excellent.

Buy some relatively cheap fish, or discarded inferior fish (but not sick fish), and put them in the tank for breeding for about a week or two.

Get rid of these cheap fish (release them or sell them to people in need).

At this point, if nothing goes wrong, your fish tank is ready.

After buying your favorite fish, soak it in a light potassium permanganate solution for 5-10 minutes. During the soaking process, you can put the container into the tank to make the water temperature inside and outside the tank consistent.

Gently scoop out the fish with a net and place absorbent paper under the net to absorb the potassium permanganate solution.

Place the fish in the tank. Do not feed them that night.

It is more appropriate to start feeding after 12 hours.

Try not to add antibacterial agents to the fish tank. If you need to add antibacterial agents, please give priority to sea salt.

If you notice your fish has a swollen abdomen, you should first consider whether it has gastrointestinal problems and then whether it is pregnant.

Adding furazolidone to the tank is the best way to treat gastrointestinal diseases. However, this will destroy the nitrifying bacteria that have been cultivated with great effort.

But it doesn't matter, nitrifying bacteria are relatively easy to cultivate :)

If the tank is large and the fish are few, the circulation device can be started at a fixed time, usually after feeding. If there are many fish in a small tank, it is recommended to start the circulation system 24 hours a day. (For tropical fish, automatic heating cannot be stopped)

In addition, it is recommended to feed fresh feed such as fish worms.

It is worth mentioning that when raising fish, we should pay attention to the density of fish per unit area. There is an old saying that "wide water breeds big fish". As for how many fish to raise in a certain area, it is difficult to have a fixed rule.

3. Water plants are just for decoration, it doesn't matter if there are any. If you want to grow them, it is recommended to grow taller water plants.

4. Small tropical fish are relatively easy to keep. As long as the water quality and temperature are controlled, they are generally not prone to disease. Gastrointestinal diseases are more common, mainly related to water quality. I personally think that Furazolidone is a common medicine. After each water change, you can add one or two pieces of it to the water. It is beneficial and harmless.
