I volunteer at a reptile store and someone brought in a tiny gecko that they had found in their produce. He is breathing but moving very little. He looks like some sort of day gecko and I desperately want to save him. So far I have been keeping him warm and I gave him a small, warm bath hoping to help him. He is slightly more active when overly warm, wiggling a tiny bit, but i don't know how to help him. Can anyone give advice?
