What a cute little guy, he's gorgeous . He doesn't look unhealthy, and seems to be eating fine he might just be a grower not a shower . I have a little royal too, perfectly healthy and kept at the same temp/humidity as my female but he recently has taken a stretch, he's just turning 3. The humidity I can't really comment on as ours is always stable without doing anything to it, but we recently tried to add bark substrate for a little decor to the carpets viv and the humidity went sky high, also coconut husk I've seen many people mention is also really good for humidity. Just thought I'd chime in and say there's still time for the little one to grow at his own rate
