Guppy, weird tail

[Regen311]

I inherited 4 baby guppies when my sister's guppy had babies and she didnt' have room for them. All 4 of them are very healthy and active. However, as one of the guppies started to grow up, I noticed that her tail bends down. While the other guppies have straight bodies, this one just has a weird bent down tail. Her spine is straight (she's a black tuxedo, so I can pretty much see through her) but it just look lik ethere's a samll a rch up at the base of her tail and a small hump then her tail bends down. No bent spine though. She seems active and happy and I noticed this a couple weeks ago, so she's showing no signs of sickness or anything. Any ideas?

I have a book on livebearers that says physical malformations can be caused by inbreeding.

wonderful. I'm sure that's waht it is. Her guppy probably was in a tank with its brothers/sisters at the pet store and got pregnant there. Thanks! At least I know the guppy isn't dying.
