what happen to my guppy fry?

[fishluver]

I have been noticing one of my gup fry is looking a bit different from what she did yesterday....with in the past month her little body is bending like a check mark... When she swims through the water it looks like a v shape now(a little wider than that) Wonder what happen and she is the only one out of 100's of fry

As guppys tend to be intensively inbred it is quite common for them to have spinal deformities etc.

If you're sure that she's not been sucked by the filter intake or attacked by another fish or anything ike that then it's probably a deformity.

Is she eating OK?
