It obviously is to some people![]()
This trait actually is genetic. That's how sweetheart parrots began. Those who began tail cropping were copying this mutation, as it is easier to just crop the tails than to breed true genetically tailless fish. The same mutation has popped up in discus and angels.
I have a true tailless fish, her dorsal and anal fins meet in the back and actually overlap a little... her backside is very clean, it's obvious looking at her that she was born that way. A pet shop nearby gets ones with cropped tails though and the difference is clear, very sad![]()
In fact, anglers and biologists were truly surprised by another tailless fish brought in one day. It is actually a spotted seatrout (Cynoscion nebulosus) that displays a genetic mutation or developmental anomaly producing taillessness. Somehow this one survived to adulthood and may have even spawned.
...and butterfly discus, which are bred not to have tails (this makes it very difficult for them to swim).
