The XS hides ended up being too small for him, he's using the M size plastic hides, w/ crumpled up paper towels inside for added "tightness." He went to his cold hide already, so I guess he approves of his hides. Temps and humidity in his tank are still stable and holding, because of the high humidity outside his humidity went up to 77% but I'm not gonna worry since now I know it'll come down during the hotter days, indoor temps fluctuate so much in this country because the weather is what it is, changing into drier substrate was a rly good decision.
