Have you talked to the seller? What was he eating for them and how often? I wouldn’t offer food too often. Once a week and try a smaller prey item as not to scare him.

is he surely captive bred? There seems to be few of those. If so you are lucky. A lot of “farm bred captives” which to me is just a marketing phrase.

Are you using a hook to approach? You will want to this animal is by far my most electric and I have a few that you’d say really more so than x and yes really.

thankfully my guy has always had an appetite unless in shed. Have you tried to soak him? Some warm water and I actually mix in the plain pedialyte. It may help him pass anything and hydrate.

They are not known to be the friendliest snake and usually get a bad rap. My guy runs, musks and will sometimes strike the hook once out and I let him run through my hands a few times he’s really not too bad. He’s never stuck at me but he does spook easy and flail a bit.

get a hook going and see how he does w the adjusted temps and a soak. Then offer some smaller food items and see how he does after you ask the former guy what he was feeding
