1, water quality
Raising lucky fish needs to pay attention to water quality to avoid changing water too much and changing water too cold. If the water quality is not good, you can use the water quality filter to filter the water again, and add fresh water frequently, usually 2-3 times a month, adding 10-20cm each time. Before adding water, put the old water first, and increase the frequency and quantity of changing water in summer.
2. Water temperature
Theoretically, the water temperature of lucky fish can be 22-32 degrees, and 26-29 degrees is the most suitable.
3. Density
Although there is no limit to the number of lucky fish, they are a little fierce and easy to get sick. It is best to raise it alone, and the density should not be too high. Pay attention to give them enough space.
4. Don't seal it
Fish tanks should not be closed for a long time. When the weather is clear, the heat preservation cover can be properly opened to facilitate air exchange and circulation. Oxygen machines and heaters are also needed to increase oxygen and temperature in time, or for first aid.
Step 5 feed
Lucky fish should be raised to ensure food nutrition. The food requirement is fresh feed with high content in protein, and rotten or malnourished food is not allowed. At the same time, we must ensure the quantity of food. Lucky fish are omnivorous and not picky eaters, but they need to be fed on time. Generally, live fish and shrimp can be fed, as well as feed, breadworms and so on.
