Do you want to keep a scavenger in the filter cylinder. There is only one purpose for raising scavengers, that is, to improve the water environment, but the effect is only temporary, because it can be eaten and pulled, and the water quality will deteriorate after a long time. The filter cylinder can keep the water flowing, and there are enough filter materials to maintain the water quality, adsorb harmful substances in the water and ensure the health of fish, so scavengers are not needed.

1. Fish tank: If scavenger fish is raised, it is necessary to prepare a suitable fish tank first. When scavengers reach adulthood, their length will be about 25 cm, so it is necessary to control the number of farmed fish tanks according to the size of fish tanks. Scavenger fish is not suitable for mixed culture with other fish. If mixed culture, it may eat the eggs of other fish, or even eat fish smaller than it directly.

2. Water quality: The water quality of aquaculture scavengers also needs attention. Weakly acidic or neutral water will do. Then there is the hardness of water, so soft water can be selected.

3. Water temperature: Because scavenger fish is a tropical fish, controlling water temperature is an important step in the process of culture. Specifically, it is ok between 22 and 28 degrees. Among them, about 26 degrees is the most suitable. If the temperature is too low in winter, they will freeze to death easily, so it is necessary to adjust the water temperature.

4. Feeding: Although the scavenger can use the garbage in the fish tank as food, he still needs to feed at ordinary times. But you don't need to feed it every day, just about two or three times a week. There are many foods that can be fed, such as moss, algae and earthworms, and plant or animal feed can be used.
