swordtail switch

[HeatherSweetness]

My biggest fattest female red swordtail decided to be a boy...

Seems like overnight I woke up and checked and she has a poker now.

Her little boyfriend doesn't seem to understand yet..I don't either...7 months old and I guess she didn't like being a girl!

The same thing happened to my female swordtail! After I got her she ended up turning into a male. From what I have read its just late development which sometimes happens in swordtails. It ticked me off when it happened to me, I wanted to breed swordtails.
