Hi i have a beardie about 10 months old. He isn’t wanting his crickets and not so much his roachea and worms as of lately. The only thing I see is a lil black speck on the tip of his tongue and a lighter color around it. He isn’t eating much of his salads. He eats more when I hand feed him. He is staying on the cooler side of his tank more. He has been glass surfing. I did get a puppy and I am not sure if he is stressed or sick. He is not out of his tank near the dog. Any help would be appreciated. Oh and I have been using Betadine/iodine on his mouth since I seen the spot 2 times a day.
