Dragonets are not at all closely related to gobies. The word is "genus," and in this case, dragonets are not only in a separate genus, they are in a separate Family and Order from any blennies or gobies. For example, a yellow tang and a channel catfish are in different orders within ray-finned fishes...so pretty far apart.Ther called mandarin* gobys I have one. The blenny is still a cousin of the goby.. they are genetically related scientifically speaking.
They both stem from the same genius. Have just evolved differently due to environment.
Thus making blenny more or less a sub category of goby.
