Agree that different people have different liking to things. I see Axi as ugly looking thing (don't know what to class them in) that stay on the bottom most of the time and occationally struggle to the top only to end up at the bottom of the tank again.
As for the condition making life hard, they eat, swim, breeds normally. I suppose you can somehow compare them to woman with big upper body parts and ask them the same question
