Matters needing attention in raising ornamental fish 2 How to raise ornamental fish

1. Requirements for water temperature and water quality of ornamental fish Goldfish are cold-blooded animals, and their body temperature changes with the change of water temperature, but the requirements for water temperature of goldfish also have an optimal range (15℃-25℃). If the water temperature is lower than 4℃ and higher than 30℃, goldfish will get sick.

Water is the environment for goldfish to live. Every time water is changed, the temperature difference between the fresh water in the fish tank and the old water in the tank should not exceed 65438 0℃. Pay special attention to the temperature difference between day and night and the change of water temperature in winter and summer. If the water temperature changes dramatically and the temperature difference reaches above 5℃, the health of goldfish will be affected if measures are not taken in time. The residual chlorine in tap water has a strong stimulating effect on goldfish, so the tap water for keeping goldfish must be kept for more than 48 hours before it can be used after aeration. In summer, the residual bait, feces and dirt in the fish tank should be removed every day, otherwise the water quality will turn sour and the dissolved oxygen will decrease, which will cause goldfish to float, which is a great threat to goldfish suitable for weak alkaline water quality.

2. Feeding method of bait: Goldfish are omnivorous animals, and their favorite foods are live bait such as red worms, water fleas, water worms and rotifers. After these baits are fished out of the river ditch, they must be washed, sundries removed and disinfected with reddish potassium permanganate solution for about two minutes before feeding. The red worms fished back in summer and autumn are scalded and dried in boiling water, and their nutritional value has not decreased, so they are the best backup bait for goldfish.

When feeding synthetic bait, you must not rot and deteriorate. Cookies, bread, steamed bread, etc. , single nutrition, easy to muddy the water, generally not suitable as a common bait for goldfish. Goldfish should be fed regularly and quantitatively every day, and eaten within 1-2 hours each time.

3. Prevention of diseases of ornamental fish. Newly bought goldfish must be disinfected. The method is to use brackish water at the same temperature or 10-20ppm potassium permanganate solution for medicinal bath 15-30 minutes. After the medicated bath, the goldfish were fed separately and observed for one week. Only when everything is normal can they be put into a fish tank filled with water at the same temperature.

Goldfish should be disinfected regularly during feeding, generally once every 1-2 months, and can be soaked in 2% salt solution or 10ppm potassium permanganate solution15-20min. Fish nets, porcelain pots and other fish utensils and containers can be disinfected with boiling water, and fish tanks and pottery pots can be soaked in 3% salt water for 24 hours, which can kill bacteria and parasites.

4, the green algae in the fish tank should be mastered moderately. Green algae (Chlorella, Spirogyra, etc.) in fish tanks. ) can protect the fish and prevent the fish from being injured by the tank wall. It can also increase the oxygen in the water through photosynthesis, which is beneficial to the life of goldfish. However, there are a lot of bacteria and dirt in green algae, which are easy to corrupt water quality, invade fish and consume oxygen at night. Especially in summer, when the temperature is high and bacteria multiply quickly, goldfish often float their heads and have difficulty breathing because of lack of oxygen at night. Long-term floating head will make goldfish weak and sick, so the green algae in the fish tank should be properly mastered and the excessive algae should be removed in time. Generally speaking, a thin layer can be kept on the cylinder wall intermittently.

5. Changes in the water depth of the fish tank The water body is too deep, which affects the sunlight and water temperature. Moreover, the low dissolved oxygen in the water and the relative increase in water pressure will make goldfish depressed and uncomfortable to swim. Shallow water will affect the free swimming of goldfish, and it will also hit the wall and cause the occurrence of water mold. In summer, if the water is too shallow and the water temperature is too high, goldfish will suffer from "hot tail disease". It is more appropriate to control the feeding water body at 15-30 cm.
