Well it will confuse him for a second, but as long as you have tight fitting hides and the space is not wide open in the tank, he will still feel secure and will continue to eat.
Basically your trying to get him comfortable enough to eat on his own consistently. When i rescued my girl from PetSmart, i put her in a 12 quart tub with a 4 inch diameter cereal bowl and a large water dish. I left her alone for 1 week, only going into the room to make sure the Ranco was working and nothing was out of the ordinary.
I never turned any lights on and kept it as dark as I could, she felt very secure being that there weren't a bunch of people walking around the tank and she could just relax. Then i assist fed twice and she had no problems.
Then i tried to just leave a pre killed rodent in the tank with all the lights off and left her alone for about an hour. I came back and she ate...every time for over 2 weeks. Then i started to offer her live rat pinkies, then live rat pups.
I know i posted this before, but your going to follow a similar path i feel and this worked very well for me. If you have a closet or another more secluded room you can stick him in where they is little to no traffic, that would be ideal.
