Welcome!!! Glad you joined!

You said he was eating live mice for the breeder, so this would be what I would stick to until he does eat. Once he's eating again regularly, maybe 5 consecutive meals, you could try switching to F/T if that's your preference.

I wouldn't sweat him not eating just yet. The move, the high traffic room, etc... may just take some acclimating. If it were me, I would wait a week and try feeding him whatever prey item he had been eating for the breeder.

If he doesn't eat the next few offerings just monitor his weight and go from there.
