Based on my observations, the WC has dark bars while the bahia has faint bars but golden body color. You be the judge. Just beware that there are a lot of hybrid bahias out there because the bahia fad is in full swing (it fish).
Here's a better profile of my bahia. I've never had or seen a WC kelberi so hard for me to explain differences. Why don't you start a thread on it? Or is this thread it?
