sorry if this has been asked. I got my eastern blue tongue skink from a reputable breeder about a month and a half ago, I think he's around 3 months old. His poop was runny when I got him but still not overly concerning. The past few days he's had bad diarrhoea (he's just started shedding as well). Still eating but not as much, today he pooped all over his good after he'd eaten half. He eats dog food with peas, spinach/kale, broccoli and other veggies with banana or other fruit as a treat once a week. He also gets garden grubs or earthworms and boiled egg every so often with calcium twice a week (the calcium is a recent thing so I thought it could possibly be a cause?) his tank temp usually stays at around 30 degrees Celsius (I have the thermometer on the cooler side of the tank) humidity is about 70, I have a box of fresh grass and dirt in his terrarium as he loves being in the grass when I take him outside but he has an obsession with eating rocks when he is outside, particularly the quartz in our garden, I won't let him eat any but I've read that it could be due to a vitamin deficiency. His water is changed daily and his terrarium is cleared of any old food or waste. I've also been told it could be from stress, my sister recently bought a slightly larger (than my lizard) northern blue tongue and she brings it around sometimes when she visits. The two of them seem to get in very well (unless there's food involved) and usually lie down together to sleep or bask so we assumed that they were getting on well but my partner suggested that my boy might actually be stressing over another lizard being in his tank. I've spoken to a vet who specialises in reptiles and she wants me to bring him in with a fecal sample but I can't do that until my partner finishes work and gets home with the car so in the meantime is love some ideas as to what might be up with my boy. Photos included, he doesn't look as glorious as he usually does. He's in the midst of shedding.
