Is there something wrong with my horsefield?

[Skyetort]

he has white lines around his shell but these can only be seen with flash. He also has some brown dots that look like stains on his shell. I’m not sure if there’s something wrong with him he’s acting normal I’ve just never seen the dots before.

The white lines between the scutes look like growth lines. Normal. And the other spots do look like water spots. My opinion I am not an expert.

Brown normal, white between the scutes is growth the other white within the scute could be too dry.
What's the humidity and how often do you soak?
