The cause of the death of the cleaner
Although the sweeper has a strong vitality, it is easy to raise it to death. There are not many algae in the fish tank at ordinary times. If you give it floating feed for a long time, the scavenger will starve to death.
Although the scavenger does not require high water quality, it is very sensitive to temperature. Generally, when the temperature reaches below 10 degrees, the street sweeper is likely to freeze to death, and it will also die of stress when the water temperature changes dramatically.
When raising scavengers, if you put a lot of salt and medicine into the tank, it is very likely that the scavengers will suffocate or die of medicine, because the scavengers have no resistance to salt and medicine. If you want to treat other fish, you need to isolate scavengers.
