My 7th grade science teacher had a pac man frog. I think it is still alive, but it has been 2 years since I have been there to see it. He would put a webcam over the tank and have it hooked up to his computer then he would turn on the projector and feed it cricuts when it was small, then baby mice when it got bigger. But, I think eventually they can get pretty big, too big for a 10g tank.
