Matters needing attention in feeding scavengers:

1. The sweeper is a tropical freshwater fish, and the suitable water temperature is above 20℃. Even in adult scavenger fish, the water temperature should not be too low. Although this kind of fish can survive at 20℃, it will not live very well.

2. This kind of fish has a high demand for water quality. Try to choose soft water with neutral or weak acidity, which has no scale and is afraid of medicine and salt. In the water where this kind of fish is raised, we should pay attention to avoid these two things, otherwise it will lead to the death of the scavenger.

3. Scavengers are omnivorous fish and can be fed with fish and worms or heterosexual feed. The fish tank for street sweeping fish should be above 50 cm as far as possible, because scavenger fish will become bigger when he grows up.

Although the sweeper sucks moss and algae, it is also a famous heavy polluter in the fish tank. Therefore, the water in the fish tank should be filtered strongly and effectively. For example, pumping with an oxygen pump for 24 hours, and conditional filtration for one day is better. Generally speaking, change the water every six to eight days, and change a quarter of the water in the fish tank at a time.
