I've read some cases about impacted pacman frogs, or those with water edema syndrome...I'm not sure whether my pacman frog is in the same situation. My new albino pacman frog has just arrived home for about 5 days. The prior owner said that he fed him feeder fish and pinky regularly, but I don't think this is a good diet so I offer him crickets instead, and only 1 feeder fish yesterday. He's been eating a lot, but around in his cage I find no poop! He burrows under the substrate for all day (I'm using coco fiber), only when I put some crickets in his cage does he move to catch the prey (his tongue is incredibly long and sticky!)-is this too inactive?. And also, I notice that his body is a bit bigger than when I first got him. Here are some of his pictures




Does he look normal? I'm new to pacman frog so I don't really know if this is a sign of disease and that his body is bloated, or he's just getting fat. Should I worry about his situation and start doing something now?
