what are you feeding him? Gutloading? What’s your supplementation schedule?
That may be the best thing for your to do. They are very hard animals to keep. Everything needs to be really spot on with their care or they can get sick and die. They are also crazy expensive to buy and provide the correct items. I think if your initial thought is to return him then you should stick with that. I am not going to try to talk you out of it. They are not fluffy personable little creatures. They are more like a fish tank, look and do not touch. If you have receipts for the other stuff you bought there you can return it if its been less then 30 days I believe. Good luck with everything.I am just taking him back and returning him.
