What would be required for a painted turtle tank? Is a 29 gallon tank large enough? Is a 40 gallon tank large enough. What is the minimum tank size for a painted turtle? Thanks

Thanks for reaching out about your turtle. There is no such thing as too big a tank, but the minimum will be determined by the size of the animal, and will change as it grows. The larger the water volume, the more stable the water quality. Turtles will probably need a water heater, haul out area, basking lamp with heat and ultraviolet B radiation.
Good luck.

    Painted turtles can become aggressive and territorial if tank size is not adequate or if there isn't enough cover (hiding spots).
    The general guideline is to provide 10 gallons of water per inch of turtle. Confirm the filter is rated for at least twice the volume of the tank to maintain water quality.
