Still not eating...

So this little guy from Bob Clark is still not eating. I received him and waited a week and would eat a rat pup live or fresh killed. I loved him from a 20
Gal set up to a 36 qt enclosure. It's not dark so you can still see it side but it's not completely clear if that makes sense. That was six days ago. Today I tried a fuzzy mouse, first tried live (snake wouldn't move) then fresh killer and nothing, he even tried to escape. Lol.

So I will leave the mouse in all night see what happens.

Here is a refresh:

Hatched 05/15 (Bob said eat rat pups)
I received Thursday June first

Hot side 89-80 on a t stat
Cool side 80-81
Humidity ( right now) 77%

Any thoughts or suggestions on my next step to get him eating?

Never had a snake that wouldn't eat

Enclosure to large. Put him in a six quart tub with a hide. I have found the single serving cereal boxes fit good and my babies always love them.

Wow I hear so many different things from people. Now a 36 qt is too big? Can you even have a hot and cool side with a 6qt tub?

With the right size heat mat I don't have a problem with it. 36qt is way to big. I keep adult balls in 32 or 41 qt
