he looks healthy. I would stop hand feeding. they will stop eating and wait for hand feeding. and they are only active at night, so he would only be eating at night. its very hard to tell if they are eating. I was even wondering if one of my geckos was eating, it didnt look like there was any food eaten, but that gecko, for a long time, gained 3g every couple days, so he was clearly eating. I agree with everything Sasha says.
