I have many Tbarbs - in 3 different tanks in many different age groups.
When I got my first TBs - I got green TBs - I got 2. (Neophyte mistake - 2 Tbarbs. Big neophyte mistake. Should get at least 5 - 7 TBarbs)
One was much bigger, and one had a much brighter orange nose than the other. The bigger one is a female, the smaller more orange one is the male. As the female matured, her belly got increasingly wide. Almost triangle-ish, and there is a light mark on the underside that seems to define where the widening has been - like a stretch mark. I asked around, just like you are doing, and learned that this is what they do - the females grow wide as they mature. If that is what you are referring to - then not to worry. My triangular girls (and I would estimate that I now have about 18 girls) are alive and swimming, for well over a year now.
But - if you are saying that the belly is swollen - and that the individual scales are "proud" which is a fancy way of saying the scales are sticking out, perpendicular, to the fish - then it is most likely bloat / dropsy, and that is not a good thing. Bloat / Dropsy - what ever you want to call it - is a term used for a variety of conditions that have the same symptom - the protruding scales.
The root cause could be bacterial, viral or toxins but the problem is that kidney function is destroyed or impaired.
With all of the medications available - I have not ever had success trying to treat fish with dropsy. Even if you were able to identify what caused the diseased state - by the time it was resolved it would be too late - kidneys can't fully regenerate.
In this case - as with most cases - the best medicine is preventative medicine, which means proper food and plenty of water changes. So let's hope that the belly issue is due to a teenage TBarb with raging hormones and not infected kidneys...
