Razor turtles are fed twice a day or once every two days. Razor turtles at different stages have different needs for food, so they need to feed different times. If the razor turtle is in its infancy, grows rapidly and consumes a lot of energy, it should be fed twice a day, paying attention to a small amount of feeding many times. The amount of each feed should be small, and it can be finished within ten minutes. If razor turtles are in adulthood, they should be fed once a day. Although the number of feeding is reduced, the amount of feeding should be increased each time. After feeding, it is necessary to clean up the food residue in the fish tank in time to avoid polluting the water quality.

Razor turtles belong to omnivorous turtles, so when feeding, they need to choose various turtle foods to provide them with rich nutrition. They like to eat fresh live bait, so they can be fed fresh live bait. However, when it is necessary to pay attention, the fresh bait should be sterilized in advance to avoid bacteria infecting the razor turtle, thus increasing the incidence of the razor turtle. They can also be fed fresh vegetables to provide them with vitamins, thus strengthening their physique and improving their immunity.
