I bought this full grown adult about 4 weeks ago. I tried feeding him a rat 2 weeks after purchase and he wouldn't touch it. I adjusted some things in the husbandry and tried again last night which would be another 2 weeks. He just wont eat. I have tried diff sized rats, pre-killed even on the first rat, he just wont touch them.

The guy I bought him from said he bought him as part of a collection from another person. Said he ate a rat 2 weeks prior to my purchase of him.

Not sure on age but he is about 1500 gram male

Husbandry is as follows
41 quart sterilite tub
Hot side 95 basking cold side 78-82
Humidity 40-45%
On a thin layer of aspin
One hide that fits him perfectly on hot side and same one on cold side (2 diff hides)
He is exposed to light for 10 hrs a day
Hasn't really been handled since I bought him since he still hasn't ate

Any ideas?
