When Madagascar rainbows start to appear and do not eat, it is very likely that they are sick. Next, I will introduce the precautions for raising Madagascar rainbows.

1. It is necessary to strengthen the management of water quality. If the deviation is too large, it should be adjusted in time. The hardness of urban tap water is generally 7. It is neutral water, the pH is mostly 6.5-7.0, it is weak alkaline water, and there will be no major changes under normal circumstances.

2. Feeding should be done regularly and quantitatively, usually twice a day, the first time around 7:00 in the morning, The second time around 7pm. In this way, the Madagascar rainbow can eat well, increase appetite, enhance digestion, and keep the digestive system working properly. Fish food must be rinsed before feeding to avoid bringing pathogenic microorganisms and harmful substances into the water. Never feed fish with spoiled fish food.
