Lower your temps to start.....90 is way too hot for any chondro. Shoot for 85 at the hot spot and 78 or so at the cool end. You can inject water in the food and that should help with hydration. Also check your ventilation. If your cage is drying out in a few hours, try to reduce the airflow a bit. You want to spray and still see moisture 10-12 hours later, but beginning to become dry. I would not suggest soaking a neo or anything under a year old. They can and will drown. Wrinkly skin is often a sign of renal damage from dehydration. Just keep an eye on humidity levels and spray more often if you have to. Good luck.
