Hi,
So i am new to the pac-man frog ownership but my frog, PJ, has recently changed from a vibrant green with brown spots to a dark green with only the very top of his body having a single strip of light green and a few small spots on the sides of his body. Anybody know what's going on? he's still eating perfectly fine, temperature is adequate, substrate gets changed every two weeks and the humidity is pretty high as i moisten him daily by spraying. he also has access to a water source and a heat lamp as of right now since we're entering weather that may be too cold for him.
