What are these small white lines on the shell?
I have a closed enclosure, maintaining 75% humidity and 95F on the basking / hot side.
Is the white in the first picture shell rot?
I also use an AC Humidifier with tap water. I will be switching to distilled water, as I did read it could be minerals that may have detrimental effects.
Anything for my tort. Thank you for reading and your time
Random: one can almost make out the letters AG on the torts head 😛
