There's been a week between the feeding efforts and I've only changed his water and paper towels. I noticed the humidity had gone up; it's very humid here during the summer, and it was around 70%, so I did some changes to his tank and now it's around 50-60%. It goes up and down though, during the last hour it's been from 49-63. There's not much I can do about it. I moved his tank to the kitchen (I live in a one room apartment, with a separate kitchen), maybe it's a little bit calmer there. His tank is covered with black paper on three sides, but the top is quite see-through and lets in some light as it consists of plastic mesh, to keep the humidity right. I'm thinking I could take him to the vet just to make sure he hasn't got parasites - it's not impossible. On the other hand, would the trip be too stressful? But I suppose it's better to make sure, anyway. The vet isn't very far away, and she's specialized in reptiles. But at least he's moving around his tank, not exactly roaming or hunting but going from one hide into another. He's not just lying in one spot. And he's drinking, too. I know there's always the possibility that he won't make it, as I just lost one of them that hadn't eaten either. I'm still hoping for the best.
