If the leo is a new one, then it is probably stressed from moving. If not make sure the tank is not constantly being annoyed (by humans always staring into it, tapping on it, running past it, loud music playing near it, etc). This stresses geckos out. Reptile tanks should be in a quiet area of the house. Make sure the tank isn't too cluttered (a ten gallon tank is really only big enough for two hides, a water dish, and a supplement dish). Bigger tanks can accomodate more. Make sure the leo has access to some decent hides where it can get away from prying eyes. If everything seems fine, then the leo probably isn't hungry. Remember, reptiles often don't need to eat as often as we think they do!!! Good luck!!!
