The white-finned blackfish is a carnivorous fish. In the process of daily feeding, it is necessary to provide enough seaweed, seaweed and other plant-based feeds for the white-finned blackfish, so as to ensure the nutritional balance of the white-finned blackfish.

When the white fin black hanging is raised in the aquarium, the young white Black fins can be tamed as bait. Add a small amount of minced shrimp and crab meat, frozen red worms, chopped spinach, etc. appropriately one by one. Because the caliber of white fins and black worms is small, the food must be chopped finely, and the meat can only be matched in moderation. It should not be too much, otherwise it will cause constipation. The frozen bait should be cooled before feeding, otherwise it will easily lead to gastrointestinal diseases. Generally, the white fin and black hanging are fed once every other day, and the amount of food should be eaten within 5 to 10 minutes. If it is an ecological tank, the feeding interval can be relatively prolonged, or even once a week, and some tiny creatures that are invisible to the naked eye in the ecological tank can also be eaten by the white-finned black hanging.
