The three taboos of keeping guppies are using drugs indiscriminately, changing water frequently and keeping them at low temperature.

1, drug abuse

It is not difficult to apply drugs to guppy when it is sick, but many people blindly use drugs because of excessive tension, which leads to guppy's death. Therefore, when raising guppies, we should pay attention to observation, share them carefully, don't blindly use drugs, and don't send guppies to the point of no return because of our own mistakes. At the same time, we should also pay attention to distinguish good varieties and avoid polyculture, especially aggressive fish.

2. Change water frequently

The guppies don't have high requirements on water quality, so change the water once a week, only one third of the whole tank at a time. If the water is changed frequently, the peacock fish will be weak and the bacteria will take advantage of it. Peacock fish doesn't require high water quality, as long as the water is not too dirty. If the feeding density is high and the water quality is easy to be turbid, it can be changed twice a week.

3. Feeding at low temperature

Guppy is a tropical fish, and the suitable water temperature is 22~25℃. Feeding at low temperature will make it difficult for guppy to survive, because guppy is a tropical fish and likes warm water environment. In winter, it is necessary to turn on the heating rod to keep the water temperature at 22~25℃. If the water temperature is below 20℃, it is difficult for guppies to survive. Therefore, it is necessary to pay attention to the water temperature when raising guppies and avoid raising them at low temperature.
