Hunger strike and force feeding

[irot9]

I got my one year old graceful a month ago. He ate about five crickets a day, sometimes more if he was hungry. It's been eight days since he's shown interest in food. I've also shown him different types of food and he has no interest.
He has pretty normal colors and up until a little while ago was drinking normal.

He hasn't had any form of nutrition in so long I feel like I should force feed him because I am very concerned. How should I go about doing this?
Thanks!

Welcome to the forum!
It will be much easier to advise you if you cut and paste the questions from https://www.chameleonforums.com/how-ask-help-66/ and then add complete answers to them.
This way, if something should be changed to perk him up, it is far easier to recognize it and let you know.
