Maybe I'm wrong...but the geneologists can "splice" many different "traits" that are physiologically acceptable to different species of, in this case fish, for example. The actual breeders aren't capable of such procedures...but it certainly looks like somebody spent some loot coming up with that "body style." And...it bares a striking resemblance to what they've done with livebearers. Same gene...different species, family, phylum, etc.?
Does anyone know if Dr. Drew contracts with hopelessly addicted fish keepers?
