1, active performance: If goldfish prefer their master, they will be very active when the master is close. For example, they will swim faster and roll. There are also some goldfish, which swim quickly in the fish tank.

2, close to the master: If goldfish like the master, they will quickly approach the place where the sound appears after hearing the master's voice.

3. Concentrate on the surface: Goldfish will swim to the surface when their master is close if they prefer it. In addition, when the owner feeds food, they will stick out their heads and wait on the water.

If breeders want to interact with goldfish, they can feed them regularly and quantitatively. As long as they develop good eating rules, they can quickly get familiar with their owners. When they are no longer afraid of their owners, breeders can try to feed them with their hands. This will be more interactive, and it will also make goldfish get familiar with their owners faster. When feeding, breeders can talk to them more often to familiarize them with their owners' voices. You can also watch them eat silently. Although you don't talk, goldfish will gradually become familiar with their owners.
