I noticed he had been very very picky in what he eats. Won't eat any of his veggies or fruits slice of apple. He likes his superworms, and mealworms

PLUS his water dish was slimy, which then seemed like he had not had fresh water for a while... Once I had new water in there for him, he nose dived into it. And has been drinking water for the last couple of days. :/ We also got him a new heat lamp bulb since the one in there did not give off any heat whatsoever.
I do not care what happens, but no matter what my animals are staying with me. For good. It's disappointing to have to rehome a pet, expect the best, and find out the best is quite shoddy.
