My steppe runner male lizard is, I believe, stressed bc of my other male lizard. He's really skinny, shedding but I have to peel him sometimes, won't open his eyes at all even when I pick him up, and also won't eat. So today I bought a new tank and added new sand heater and everything. I seperated the lizards. He's,still Blahh though. What else can I do to help him?
