Both of them require less fish in the tank, round fish are generally not filtered, and half of them are safer to raise fish.
equipment
1. For large fish tanks or other things for holding fish, the standard is 10 cubic centimeter 1 cm of fish and thermometer.
(This is a must)
2. Appropriate filtering equipment is a good helper. For example, a good water tank is full, but there are few fish. It is not necessary to suggest the filter cotton for filtering (selecting) the first layer of filter residue. I use super filter cotton (if there is an upper filter screen, it is best to use it).
3. The suitable bottom sand is not quartz sand, nor is it black gold sand for special lovers. It is good to plant grass in 3 to 4 cm (optional).
4. Some kinds of fish don't eat grass very much. For example, to grow aquatic plants, it is necessary to grow cheap and fast-growing black algae (Pteris vittata, water grass) and Sophora alopecuroides. Or aquatic plants in Shui Rong are expensive but grow slowly, and fish don't eat much, which is good for ecological balance and can be planted if conditions permit (recommended).
5. Three bacteria, used for cylinder opening and water purification. Nitrifying bacteria, yeast, lactic acid bacteria, active lactic acid bacteria (optional)
6. Heating rods, tropical fish, goldfish and koi fish with room temperature below 22 degrees in winter (optional).
7. Lamps are not required if they can avoid direct sunlight and get enough light every day (recommended).
Attention should be paid to fish farming: the water quality should be no problem, the temperature and light should be appropriate, the food should be of good quality and quantity, the operation should be gentle and slow, the drugs should be used with caution, and the toxic substances should be kept away (pay attention to the lampblack, insecticide and mosquito-repellent incense at home).
1. Don't use 1 liter water (length, width and height, 10× 10 cm) multi-cylinder and small filter to raise fish. If fish are raised with 1 cm, it is easy to get sick and die. If the fish tank is at least 30 cm above, it is easy to maintain water quality, or there is no filtering equipment, please calculate the fish according to the water surface area. Tropical fish need 30 square centimeters of water per centimeter (excluding caudal fin), and goldfish need 60 square centimeters.
2. After opening the can to lift water, it should be disinfected with strong brine, rinsed with clear water and filled with water. The water temperature in the cylinder should be between 28 and 30 degrees, and the water should be kept for 7 days.
A In this article (), it is said that for fish or people who can use nitrifying bacteria conditionally, one of the four methods can be selected. B In addition, after the tank is opened, the normal temperature of fish should be determined according to the species, survival and treatment of raised fish and aquatic plants. C after opening the fish tank, the fish tank should be illuminated, but not in direct sunlight. In addition, places where nitrifying bacteria live, such as filter tanks, must be kept away from light and ventilated (if it is an inner filter or an outer filter barrel, it cannot be stopped, such as power failure).
3. When putting the fish, pay attention to put the fish and the bag into the tank together. /kloc-After 0/5 to 30 minutes, remove the water and bag and put the naked fish in the tank. During the period, water was added to the tank several times to make the fish adapt to not feeding the day before (be careful not to let the fish have white spots, white hairs, rotten fins and scales).
Changing water depends on your water quality. If there is filtration, the number of tanks is large or small, but there is no filtration, and the number of tanks is small or large, so the water should be dried. When changing water, wash the filter cotton at the top of the filter tank with clear water (do not use detergent) (be careful not to change the biochemical cotton in the middle layer) by one sixth at a time. 10 Change water for 20 days in winter and 5-7 days in summer. Water needs to be changed under special circumstances, and special treatment should be carried out after cleaning the filter cotton. Therefore, the advantage of less fish in the tank is that it can change less water and balance the water quality in the tank.
5./kloc-finish your food within 0/5 minutes and leave bait once or twice a day. Take out the cheapest red and green grains like fish shops without oil, such as grass goldfish (red crucian carp), and even the steamed bread is better than that.
6. Be careful when using drugs, because almost all drugs are overdosed, and the fish will definitely die, even the commonly used salt. Therefore, we should pay attention to the dosage, early detection and early treatment. If an individual or a few people have problems, it is best to treat them in isolation. We must be careful when using drugs in three cylinders. Many people poison their fish with their own drugs. Third, in the process of treatment, the water temperature is sometimes appropriate and important.
Some people use water purification agents and fungicides indiscriminately in order to purify water. Here's a reminder: don't add drugs indiscriminately. Adding drugs illegally is like saying that the way to keep a person's room (without sewers and toilets) clean and not sick is to use fresheners, disinfectants and drugs. Do you think it's possible?
To purify water, it is necessary to strengthen the filtration system, strengthen the physical filtration of fine particles, strengthen the biological filtration to deal with harmful substances and purify water.
7. Some kinds of fish don't eat grass very much. If you want to grow aquatic plants, plant cheap and fast-growing black algae (Pteris vittata, Herba Sedi) and Sophora alopecuroides. Or Shui Rong, which is more expensive but grows slowly. Goldfish eat grass carp but don't eat big ones.
Buy fish
1. Don't choose thin and flat fish.
2. Don't choose fish with lesions (such as white (red) spots, white (red) spots, body deformity, scales, etc.). )
Don't choose fish without water.
Sunbathing (choose one)
1. Exposed to water in the sun for at least 1 day.
Second, there is no water trapped in the container in the dark for a week.
Three, the gas explosion more than 24 hours of water.
4. Illuminate a strong light near the water surface, and it will explode in half an hour.
