Definitely try the Pangea foods. They are very palatable. Also, if you can find out what it was eating before that might be helpful--it might not want to eat unless you offer it the same thing to start out with. The best way to know if it is eating is to look for poop. It may be eating a few licks of food here and there. Dabbing a little bit of food on the nose as suggested can be helpful as well, and then when the gecko licks it off you can hold the dish of food up for it to lick more. Ultimately you want for the gecko to eat on its own, but sometimes they need a little assistance while getting settled into a new home.
