Pearl turtles do not know their owners. Pearl turtles have a small brain capacity and do not have complex emotions like mammals. Only through long-term feeding and early training can the turtle form a conditioned reflex and let the turtle's subconscious mind Know that there is enough food here to survive.

Precautions for feeding pearl turtles:

1. Pearl turtles like higher water temperatures, and breeders usually need to keep the water temperature above 20°C. If conditions permit, the water temperature can be kept at around 24°C.

2. Pearl turtles like clean and refreshing water quality. If the water quality is too poor, they are prone to rotten skin and rotten armor.

3. Pearl turtles are omnivorous animals and can be fed with a variety of feeds to ensure their nutritional balance.

4. Animal feed must be sterilized first, and plant feed must be cleaned to avoid pesticide or insect egg residues.

5. You can usually clean the feces and food residues in the container after each feeding to avoid contaminating the water quality.
