Map fish don't bite. Although they are fierce in character, they only attack other fish, not humans, so they don't bite people in general. In addition, most fish are naturally afraid of people. If the breeder directly reaches into the fish tank, most of them will flee in a hurry and will not take the initiative to attack their owners.

The IQ of map fish is relatively high. After a long time of breeding, they may interact with their owners. Although map fish generally do not bite, it is best for breeders not to put their hands in the fish tank.

Although map fish have certain IQ, they can't interact with their owners like other pets, and can only swim up when their owners are close to the fish tank to show their closeness to their owners.

If breeders want to cultivate their interactivity, it is best to feed them in person. And feed food regularly, quantitatively and at fixed points, so that they can develop good eating habits and cultivate their conditioned reflex. In this way, every time the breeder approaches and feeds, they will swim excitedly. If breeders want further interaction, they can hold food in their hands and let them eat in the hands of their owners. This can also enhance their interaction with their owners.
