You guys are discounting looks and behavior as evolution but just because my dog and my cat may have like dna doesn't make them the same. That's just a facetious example but you get the point. Just because the dna says that on a mitochondrial level, there are similarities doesn't mean that they should be grouped together. The 3 fish that I mentioned (lyonsi, trimac, salvini) have distinct similarities that cannot be ignored. At the end of the day this only matters to scientist but I think that regularly changing genus/species is pointless.
