? Money tortoise is to be able to retreat a shell, retreat a shell is its normal physiology condition. The shell of the money turtle is synthesized by the shell-making cells in the body. When the turtle shell grows to a certain size, it will not grow any more, but the money turtle will grow slowly. When it grows up, the outermost shell will fall off. This is because the inner shell will continue to develop and grow, it will urge the outer shell to fall off, so there is a phenomenon of shell withdrawal. The process of the money tortoise shedding its shell is gradual and does not seem obvious. When the money turtle is an adult, its body shape and shell will not change any more, but it will still withdraw its shell.
1, external force retreat: Water quality is poorer, the bacterium that breeds in water can encroach on tortoise shell, then appeared the phenomenon that retreat. Moreover, the money turtle is scratched or bitten by other turtles, leaving a wound, not treated in time, easy to cause rotten skin disease, this disease will also lead to the shell.
2. Physiological state: The money turtle is the same as the snake. It has a period of ejecting its shell. Shelling is a symbol of its growth and development.
to ensure good water quality, it is best to change water every three days. Do not intervene in the process of shell withdrawal, just wait patiently for it to fall off by itself.
