Hi, my recently caught Western Fence lizard hsa some white on the front of the tail near the leg, but isn't encrusted with white. Also, I noticed he became darker. I have fed him online crickets (rly small, but not pinhead that were 3/16") and Petco crickets that he ate (and i saw him ate so its not starvation). Could he/she (i call him a he and named him Irwin) have not enough sunlight- i put him in a cage on the other side of the window. Also, could it be the food? I do not give him much sunlight, but who knows? Thanks
