same thing happened to me when i was like 16. Bp got out of its tank and was lost in my room. All i did was put a mouse in its tank with the screen open turned the lights off and went off to hockey only to have a voice mail from my mom that they had checked if he came out and sure enough he did to feed and they took the mouse out and put him back. Good luck on your find . This year one of my normals got out and she went right over to the desktop computer and was fast a sleep on top of it haha
