Well if you'd just recently obtained them then it may be likely that the poor little guy is a bit stressed out and still needs to adjust to his new home a bit more. Give em some time to adjust and try again a bit later? Other than that they look great! They even have a nice decent size tail.
Just to be safe though maybe somebody with a bit more knowledge can throw in their two cents.
I agree with KaitouCat. General rule is to handle and disturb as little as possible for the first two weeks after a gecko's home is changed. You should expect his appetite to be a little off until he settles in. Nothing to worry about.
Alright i never had one this small before hes really pale right now so im wondering if hes going into shed. My bf said we had eight of them in last night and i pulled four out this morning couldnt find any of the others
Mine does not like to eat right before/after he sheds, so that can also affect their appetite.
I'd recommend not leaving crickets running around in the cage overnight though. They can harass the gecko if the gecko is not hungry enough to eat them. A lot of people feed with tongs or let the crickets run around for only 15 minutes or so before removing them.
You might try a shallow dish full of "active" mealworms. They need to be moving , in order to catch the geckos attention. I always put a small slice of carrot in the dish with the mealworms.
As far as crickets overnight, I have never had a problem. I put three dusted crickets with a small piece of carrot in my babies tubs overnight. Just be sure they are not the big adults. Oh, and pinch off the hind legs for easy catching.:main_thumbsup:
