I'd suggest you keep it because that is a terrible picture to make any sort of judgement on. To me it just looks stressed out. Either way it is a terrible picture to use for any sort of positive ID. There are way too many factors that affect the way that fish looks.
Lighting , stress , water quality, characteristics (not all fish in a particular species are identical) and picture quality. I don't think there is enough information to credit or discredit that it is a fenestratus. Way too often people want to jump on the hybrid bandwagon. Wait and see; if it doesn't begin to show more fenestratus characteristics then don't breed it but don't assume that it's not a fenestratus because someone made a decicision based on a bad picture.
