How to raise ornamental fish well

1. Fish tanks can not change too much water at one time, which will lead to water quality discomfort. Water quality includes pH value, hardness, chloride ion, dissolved oxygen, nitrate, sulfide, protein and turbidity.

2. How to feed. The most important thing to watch the fish tank is to control the feeding. It is appropriate to eat it once or twice a day within 3 to 5 minutes. Feed less in cloudy and rainy days, not at night. Fish in the process of digesting food need to consume more oxygen, rainy days, night pressure is lower, the dissolved oxygen in the water is also low, so feeding the fish may lead to serious hypoxia in the water and death of the fish. Most of the dead fish occur at night, and severe hypoxia in the water is one of the main reasons.

3. Bait must be clean, which is the easiest thing for beginners to ignore. Feeding unclean bait can easily lead to fish disease. It is recommended to buy brand frozen fresh foods produced by professional companies, such as hemoglobin, harvest shrimp and so on. Although live worms such as water earthworms and water red worms are the favorites of fish, they all grow in a polluted water environment, and they are easy to die and rot in temporary culture, so it is necessary to be cautious in putting live food.

4. Keep the water clean. After eating, fish will consume a lot of oxygen and discharge a lot of waste, polluting the water and breeding germs. In order to keep the water clean, efficient filters must be installed. If it is a bare tank fish culture, but also use to remove excreta from the bottom of the tank at the same time for 1/10 or a little more old water, especially in summer must not be ignored. For the ecological tank of fish and aquatic plants, you only need to change 1ax, 3pm, 1pm and 4 water once a week. The filter is designed with inflation, so that filtration and inflation can be carried out at the same time, which not only purifies the water, but also replenishes the oxygen. However, the water tank should not be inflated.

How to choose healthy ornamental fish

1. Don't buy thin fish. Because from the front of the fish, we can clearly see whether the meat on the back lacks healthy luster, usually we have to choose healthy and lively fish with glossy back.

2. Don't buy sick fish. White spot disease can be seen, other diseases are difficult to see with the naked eye, which can only be distinguished by the experience of fish farming. If the elephant fish is hiding in the corner and breathing fast, it is very likely that it is suffering from egg flagellum disease, so do not buy such fish.

3, the color of the fish is not good, the fins can not be unfolded, swimming posture is like floating fish, do not buy.

4. Observe how the fish eat the bait before buying it. Among the same kind of fish, the fish that pounce on them with bait have a good appetite and must be healthy and vital fish.
