Sharks cannot recognize their owners. The brain structure of sharks is too simple. When they grow up, they will not even remember their own mothers. This is the law of survival of sharks. Moreover, sharks have a fierce temperament and are not interested in humans, although they will not actively attack humans. But there is a certain danger.

Methods for breeders to correctly feed sharks:

1. The fish tank for raising sharks should be larger, with a length of 2 to 5 meters and a width of 0.8 to 2 meters. meters, the water level height is about 0.7 to 2 meters.

2. Put some coral stones and coral sand at the bottom of the fish tank, and keep the water temperature at about 25 degrees.

3. Because sharks are marine animals and cannot be cultured in ordinary fresh water, some sea salt must be added to the water. The concentration of sea salt mixed with water is between 1.020-1.025, and the pH value is maintained between 8.0-8.5. The space is most suitable.

4. It is most suitable to feed sharks with quick-frozen squid. You can also feed some shrimps with their heads cut off. If your fish tank filtration system is good, you can feed some live fish directly.
