Thanks! His tail is pretty skinny, but I've only had him for about a month, and he went through a week and a half adjusting period without regular eating. He definitely has been hungry and hunting after mealies, and has been eating around 2-4 a night (getting better over time), and also just had his first shed. Hopefully his tail will grow soon!
Just keep feeding him/her =) some times they take a little while to put the weight back on after a weight loss like that. Keep it at the right temps, offer calcium powder with the mealies and plenty of water.
