Betta Missing Part Of Anal Fin

[Platy lover]

My cellophane female looks like she was never born with part of her anal fin. Is this a common thing?

It doesn't look like its a problem or anything.. It may just be how she was born.. but if you've had her for a while and you just noticed it then it is a problem.

I bet that she just.. doesn't have it or her previous owner (if she had one) may have had an accident if they bred her and it got torn off.

I think it is a birth defect, I mean there is no indication that it was ever there.
