Earlier when I was just observing my pleco, I noticed his belly seemed like it was closer to the glass then where the bottom of the tail is. It is completely not noticeable unless he is swimming where you can se the bottom of him or he is on the glass. He still acts completely normal and I haven’t noticed anything else. Is he just fat, or could there be something wrong. Also he is pretty small, maybe like 2 to 3 inches if that changes anything. I am probably worrying over nothing but I figured why not check with other people.
