Don't let the picky eating discourage you. Keep trying. Like everyone says they are all different. I have one the first time he ate for me I had to turn off all of the lights and feed him by flashlight. He wouldn't eat any other way. A month later he wouldn't even eat in the darkI finally tried a live mouse. He won't eat anything else but live now. I don't have to turn out the lights but he wants his hide so he can drag the mouse inside to eat. Then here recently one of my boys that never misses a meal decides his mice aren't good anymore because it must have smelt like a rat because I thawed them out in the same water
I gave him a live mouse the other day and bam. Get your husbandry straight and try again.
