A. Cacatuoides Female Health Query

[kyleb2003]

Bought a couple of apisto cacatuoides females about a week ago, didn't notice at the time but one of them has a humped back and I'm wondering how this could affect her, she seems to be doing ok so far, eating, flaring her gills at the other and her fins at the male. Pictures below:

She will probably be fine (I think it is a case of stunting) but I wouldn't use her for breeding.
