My guppy is about 8 months old (I got her from a friend so I don't know for for sure how old she is) she developed a bent spine and I don't know why. Any ideas? She is eating and acting normal it has been this way for a while at least a few months. It looked like she got tired of holding her tail or back half up and so let it droop and now it seems stuck that way. Another guppy I have the white clearish one with the orange tail she too is at least a year old and I am starting to notice the same thing happening to her.
