Honestly James... I also think you did the right thing. Granted that there is a lot of variability in how the offspring look, but if the mother looked poor, there's no reason to suspect that the father looked any better if they came from the same region (in the wild). There are such pretty parietalis out there that I'd just buy one you're happy with instead of keeping a mediocre one for the next 5-10 years.
