Roy is a spur thighed. I was just looking for advice as to whether their shells do change colour. A colleague tells me they can alter and not to worry. I'll take his advice I guess.
Not sure if i should be concerned so any advice is appreciated.
The first pic is his shell mid March this year. Second pic is today. It's changed from a lovely dark pattern to very patchy almost pale green patches in a couple of months. He's eating, pooping, doing everything he should. Sunshine...
