In my opinion no. But one thing that happened with my little guy whose a little younger then your was he was getting fat like that and i thought it was he was just full but he was constipated. i was worried . if you haven't seen poops in the tank then you will know hes constipated. i put my little guy in a bowl of warm water and massaged him a little and he pooped. aka deflated in size. i don't know why this happened (don't know why he was constipated i mean) but this works well, warm water and whatnot. good luck though i couldn't see the tail but that's how you know about constipation. is a fat swollen looking tail it only seems to happen before a shed in the pink belly stage. hope this helps.
