Illness/Sickness: My tiger salamander isn't eating

[ZekeSalamander]

I noticed a few days ago that Zeke, our tiger salamander is losing weight and now he isn't eating. He was also trying to bury himself a lot and now he won't get out his little tub of water. I've tried dangling the crickets (the only thing he would eat for awhile) and he still won't eat. May sound silly but I love the little guy and I am extremely worried. No vets around where I live will see him. Please help!

We've had him about 3 months now and I've followed all the advice given on here. If you need more info ask. I just need help. I've read several other threads and haven't seen anything pertaining to him specifically. Please any ideas would help. Thanks!

What is your setup like? How warm are you keeping it?
