My thoughts, exactly. However, "gold saum" is one thing, but I'd like to see someone show me a "golsom" cichlid in any cichlid literature in the English language... maybe golsom translates gold saum in Clingon or one of the Middle Earth languages, but otherwise I have to wonder what hat they pulled that out of...
As far as false and true green terrors, pretty much in the eye of the beholder imo, considering that, as mentioned above, "green terror" is not a scientific name in the first place, but a nickname that's been applied to what's turned out to be more than one fish. Knowing the history in the hobby of the fish and/or name is one thing, but imo getting into arguments over which is "true" or "false" is like arguing over who called first dibs on what is essentially just a hobbyist nickname in the first place.
