Pacman frog

[monster]

Yes they can get big, I don't know if they get exactly as wide as long but if you go look at some pictures of full grown pacmans some of them do look that way. And im not positive if shedding would affect there appetite. I know I have seen my girl shed and eat it then eat a full nightcrawler the same night. I noticed u said u had them in a 18x18x18 exo terra tank. There not in the same tank are they? If so I would get the little one out of there and in his own enclosure. Having 2 in the same tank is big no no, the bigger one will eventually try to try eat the smaller one, and if he cant fit it down the hatch it will end up hurting the smaller one more then likely. And if they stopped eating or one has that's probably why, they are stressing each other out and it wont be good in the end for one of them. And if there not in the same enclosure disregard what I just said.
