Hi. I have a two-year-old male beardie named Peapod. He is currently fighting some nasty pinworm and I noticed the tip of his tail is a little darker than normal. This could be from stress, but I tend to get very anxious about anything being potentially wrong with one of my sweet beardie babies. I tried washing his tail off a bit with warm water to see if the color would change, to no avail. His tank is very clean and he is still active (he is happily running around the living room as I write this). Here are some pictures. Any thoughts/advice would be so incredibly appreciated! (He is a little on the thin side as he has barely been eating because of pinworm )
