Point taken, but having a dorsal fin thats 30 or 40 times bigger than it's supposed to be can't be that comfortable either. Also, balloon shaped fish are fully capable of living long, full, and for all intents and purposes, normal lives if their needs are met. Coming from a fancy goldfish background, it peeves me a little bit that people badmouth certain traits, such as the "balloon" body, and the same people often won't bat an eye at hm bettas or guppies with such extreme finnage that they can hardly swim.
