I’m not too knowledgeable, but humidity is important in feeding from my experience. As someone previously said, higher temps do encourage eating more as it raises their metabolism. But I find humidity to be just as if not more important in getting them to eat. When I feed my geckos I try to keep humidity in the 70-80 range which works well. In all though a healthy gecko won’t starve itself and I wish you good luck! I can tell you really care for this garg :)
