"Balloon" fish are, in fact, deformed fish. They have shortened, curved spines which can cause difficulty swimming, and IME they tend to be more sickly overall than non "balloon" fish. Sadly, "balloon" fish are being farmed now because people think they are cute and they can charge more for them than a normal fish of the same species. I was not aware that balloon platies were available, although it would not surprise me.
