Do map fish need oxygen? Do they need a heating rod

Breeding map fish generally requires oxygen. However, if the number of map fish is relatively small and there are only one or two, there is generally no need to use oxygen. You can change the water frequently and use the filter pump regularly. However, if the number of map fish is large, then oxygen is needed. Generally speaking, only the oxygen pump needs to be opened during the day. However, if the map fish is really dense, it needs to open the oxygen pump for 24 hours. 1、 Does map fish need oxygen? When breeding map fish, a very important aspect is to provide oxygen. If the oxygen is insufficient, the map fish is likely to die due to lack of oxygen. Breeding map fish generally requires oxygen. However, if the number of cultured map fish is very small, when there are only one or two, you can not use oxygen. At ordinary times, pay attention to changing the water regularly. If you use the filter pump regularly, you can provide enough oxygen. However, if the number of map fish is very large, it needs to be oxygenated every day. Generally speaking, it only needs oxygen during the day, and it does not need to be open all day. However, if the map fish are really dense, it is necessary to open the oxygen pump for 24 hours. At the same time, we should also pay attention to water change and other problems in order to provide sufficient oxygen for the map fish. 2、 Do map fish need a heating rod? When breeding map fish, it is necessary to keep the water temperature appropriate. Map fish still have high requirements for water temperature. Specifically, the water temperature between 25-28 degrees is the most appropriate. If it is lower than 20 degrees, it will have an adverse impact on the growth and development of map fish. Below 18 degrees, it may die. Therefore, when it is lower than 20 degrees, it can be heated with a heating rod and adjusted to the appropriate range of water temperature. Generally speaking, only the heating rod needs to be used in winter, and the water temperature in other seasons generally meets the requirements. （DeTuYuXuYaoDaYangMa，XuYaoJiaReBangMa）
