Fancy guppie's with a bad back!!!

[imrandome1]

Well yesterday one fancy guppy had a back/fin what ever you wonna call it, that would curve down and straighten out again? then today another yellow guppy had a curved back? They have been resting on the rock's, but then are fine again, as well as this i lost the pleco, it had sunken in eye's and did nothing but swim a little. Is there a med or a way to stop other fish from getting the strange back?

Thanks.

By curved, do you mean curved like an 'S' or just bent, like downward?

Sometimes guppies aren't very healhty and are inbred which can cause skeletal deformities to happen. Are all the fish acting sluggish, or just the guppy? Have you tested water quality lately? How often do you do water changes?

Water is fine, first thing i did, water changes once a week 45%, its more of an S curve, the gourami are fine if anything very jumpy, but the guppies do rest on things sometimes, but as soon as I walk past they are get up and swim looking for food.
