1. Swim back and forth: goldfish will swim back and forth when they are hungry, and their foraging state will be very obvious. If there are moss or aquatic plants in the fish tank, they will keep eating.
2. Stretch your head: When goldfish are too hungry, they will stick their heads out of the water to prey on mosquitoes and microorganisms on the water.
3. Follow the master: If the goldfish is farmed for a long time, when the master approaches, the goldfish will actively follow the master, and may roll or shake its tail. If the breeder feeds them a little food, they will eat it quickly.
