Hi, I am new to geckos, my little guy doesn't seem to want to eat, I got him to eat one little cricket the other day and I have left mealworms in his bowl all day and night but he hasn't eaten anything for two days. I even left a cricket in there overnight, not my favorite thing to do because I know they can bite him but I thought maybe he would eat at night since seems to be up at night more. But no such luck. We just got him Saturday so I know he might need a little while to adjust, but how long do I let him go without eating before I get really worried? He is so little only about 4 inches long.
