There may be many reasons why map fish have no spirit and don't eat. You can first test whether the temperature of the water in the tank is appropriate. If the water temperature is too low, they will have no spirit and will not eat. If the water temperature is normal, it is necessary to check whether their bodies have symptoms such as white spots, ulcers and rotten gills. If so, they may have enteritis, which will also lead to this phenomenon. In addition, map fish are frightened when changing water, or when they just come to a new environment, they may have no spirit and no food.

There are many reasons why map fish are energetic and don't eat, which need symptomatic treatment:

1. If the water temperature is too low and they don't eat, they need to open the heating tube, increase the temperature and keep the temperature between 18 and 26 ℃.

2. If you don't eat because of enteritis, you need to choose to treat it. You can choose gentamicin, oxytetracycline and other external medicines, dilute them and sprinkle them in a water tank for treatment.

3. If you don't eat because you are frightened, you can lure it with fish food in front of the fish tank, make it interested slowly, don't beat the fish tank, and don't let people walk in front of the tank frequently.

4. If you don't eat because you have just entered the new environment and haven't adapted, keep quiet, try not to disturb it, and let it adapt to the environment slowly.
