Scavengers are a group of fish also known as benthic fish. They mainly live by eating the debris and rotting materials at the bottom, and play a role in cleaning the fish tank. Therefore, scavengers can be kept in fish tanks.

The following points need to be noted when breeding scavengers:

1. Tank size: scavengers need enough space to move around and feed, so it is recommended to choose a larger tank.

2. Water quality management: Scavengers have high demands on water quality, which needs to be kept clean and stable. Regular water changes and water quality tests are necessary.

3. Feed selection: Scavengers mainly feed on the bottom debris and decaying materials, but can also provide a moderate amount of fish food as a supplement.

4. Grouping: Scavengers are schooling fish, so it's best to choose more than one to keep them together to ensure their socialization needs.

5. Aquarium Decoration: Provide proper aquarium decorations such as rocks, caves, etc. to provide scavengers with hiding and resting places.
