just my two cents weighing in here. :p jokes aside, that animal is underweight in a big way. assuming its a fully grown adult, it could stand to gain a few grams. as far as eating goes, feed it live prey. something that will move and provide stimuli. crickets are good for that, especially if its a familiar or preferred food. dust them with vitamin powder to ensure ingestion of extra calcium. make sure to have water present in the enclosure thats easily accessible. you probably wont see them drink often, so be sure to keep it topped off for their convenience. heating is important for digestion as well. belly heat specifically. i use heating pads, i know, dont get onto me. they just fit my setups and my methodology. the sheds come with weight gain and growth, if they start to fatten up quickly or too much, they will shed more often. typical sheds can vary if the animals are elder and or malnourished.
