So I recently got a crested gecko at a reptile expo. I have read up on their care but have never owned one before. Ever since bringing him home he just sits in the same spot in his bib and never moves. I’ve changed his food twice and I don’t think he’s touched any. He is a 4 year old 50 grams adult male. He still has his tail and is current if living in a 12x12x18 bib. The breeder I got him from says that he recommends no lighting because it can stress him out so my crestie doesn’t have any. Any advice on how to get him to eat and stay healthy would be greatly appreciated. Thanks!
