The bigger and more expensive the yellow-forehead turtle is because the purebred turtle is not very big, and its body length is generally between 83-186 mm in adulthood. If the body length of yellow-forehead closed-shell turtles exceeds 186 mm, it means that they are probably cross-species turtles, so the price will be relatively low.

Normally, purebred yellow-brooded closed-shell turtles are bigger and more expensive, because they need more resources and costs from infancy to growth, such as food, treatment expenses, breeding containers, etc. In addition, it is easier to raise yellow-forehead turtles when they grow up than when they come to water when they are young, so the bigger the purebred yellow-forehead turtles are, the more valuable they are.

Wild yellow-fronted closed-shell turtles can't be raised, because they belong to the second-class protected animals in China, and have been listed in the List of Terrestrial Wild Animals Protected by the State on August 1, 2000, and can't be raised, sold or hunted without permission, so it is illegal to raise wild yellow-fronted closed-shell turtles. However, this is only for wild yellow-forehead closed-shell turtles, and artificially bred turtles can be raised normally.

It is difficult to raise and reproduce yellow-forehead turtles. Breeders should pay attention to water temperature, water quality, feeding and environment during breeding, so as to ensure their normal survival.
