Meaning the main thick black bars are split into 2 smaller bars? That would certainly be a non desirable trait like when they have "mooning" in the bars. Fish like that are culled by reputable breeders. Though with small fish that fronts are typically sold at it can be hard to tell how they will turn out and you klinda cross your fingers and hope to get those perfect bars. I know the guy I bought my colony from spent a few years and many different groups of fry to finally get the "perfect" group.
