Black fin sharks are very easy to raise, and individuals below 1250px are very easy to adapt to the artificial environment. They like to eat fresh cuttlefish and cod meat, and they can grow quickly as long as they are fed 2-3 times a week. Use a larger box when transporting black fin sharks to ensure that they can move normally inside. Don't turn on the light immediately after the new shark enters the aquarium. Sudden light stimulation may frighten it. After being frightened, it may swim quickly, hit the glass and go into shock or die. Don't put too many rocks in the aquarium. When sharks swim, rocks can easily rub their eyes. The aquarium for raising black fin sharks should be at least 5000px long and 2250px wide, because they can grow to more than 1750px within one year. If there is insufficient swimming space, it is likely to cause spinal deformity.

No matter what kind of fish meat you feed the black fin shark, you should ensure that the bait is hygienic. It would be great if ultraviolet rays or ozone were used to disinfect the bait. Don't feed sharks with freshwater fish. Most of them contain deadly parasites and bacteria. After being infected, sharks will cause many diseases, such as enteritis, endoparasites, loss of balance, etc., and take their lives. It is necessary to add iodine-containing drugs to the bait once a week to prevent the occurrence of thyroid diseases. It is best to add some comprehensive vitamins at the same time. Although it seems to have no effect, after a long time, you will find that the resistance of black fin sharks has improved significantly.
