I'll risk saying things you probably already know, but here goes, hopefully someones benefit. I recognize you are regular on here, and do not mean to be condescending at all, however, sometimes we forget things when we are concerned. Please take my suggestions with a grain of salt.
Also keep in mind I am not a dumerils expert by any stretch of the imagination. My BP, Shayna, can be a shy eater sometimes, as can my Scaleless corn, Solana.
Check-list
1. Dark, dark, dark. Feed at night, dark room, etc.
2. Make sure he feels secure otherwise - hides, etc.
3. Temps and humidity dialed in.
4. Try leaving the (F/T) prey overnight?
5. Scent the area (let the F/T prey sit next to the tank for a bit before feeding).
6. Try different prey (adult mouse if rat pups aren't exciting him right now)?
7. Any chance he is in, or going into, shed?
It can be stressful when you are seemingly doing everything right and an animal won't eat. I am thinking of you guys and pulling for you.
