in a few years. If the map fish is raised normally, it can grow to 30cm in 2-3 years. Their growth rate is very fast, as long as the living environment is comfortable and food is sufficient, they can grow 10-15 cm in one year and 20-30 cm in the second year. However, if the fish are not properly raised or raised by novices, their growth rate will be slower, they can only grow 5-10 cm a year, and it will take 3-4 years to grow to about 30 cm.
1. Water temperature: Map fish do not require high water temperature, as long as the water temperature is kept at 22-26 C, they can survive well. However, in the process of feeding, attention should be paid to the temperature difference, because too large temperature difference will stimulate them and affect their growth and development.
2. Water quality: Map fish can be eaten and pulled, so it is easy to pollute the water quality. It is better to install a filtration system when raising map fish. At ordinary times, water should be changed frequently to avoid bacterial infection caused by poor water quality. The disease of map fish can also affect the growth rate, and breeders need to prevent it in advance.
3, feed: The appetite of map fish is bigger, want to let them grow fast, can feed a few ox heart, loach, small fish, shrimp, chicken, pork to wait more. However, they should not only be fed with these foods for a long time, but also with synthetic feed, so as to ensure a balanced nutrition and accelerate their growth.
