I was thinking impaction because his stomach sometimes looks uneven like it’s down on one side and not in the other. No substrate but I am using FAke plants, What small real plants will do well because his Cage is not by a window.
My 2 month old Chams stomach has been a little saggy and uneven as if something was stuck in there. He’s eating pinhead crickets so I don’t think they are too big for him. First photo is how he looks and 2nd is him just after eating a cricket.
