A rose queen is a morph of flowerhorn.
It gets confusing because Usually the only physical differences between the red devil and midas are that Red Devils have thicker lips and typically have more pointed mouths. Other than that they will generally appear the same. It can also vary from specimen to specimen and i am sure alot of times when we see red devils they may actually be midas cichlids and vise versa. Chances are too the red devils or midas cichlids we buy may already be hybrids (i think mine probably is) between the two because they tend to be hard to tell apart. So my guess is if you bred a midas with a devil there would be next to no difference. So it would be hard to say. Once they get a little bigger than this it gets a bit easier to tell. Mine looked like this for a while than when it got bigger it got in alot of white colouration with bright orange patches.
Unless you purchase them from a reputable importer such as Jeff Rapps or Gage from Cichlid Connection then they're nearly guaranteed a hybrid. The fish you see today are a result of poor breeding techniques which makes a positive distinction between the two species almost impossible. So yes when you breed the fish you see today there will be little differences, but do that with a wild caught species of each and there will be changes which will slowly deteriorate into what you see today when the dominant gene continues to take over.
There are also more individual characteristics than large lips, there is fin and head shape, nuchal hump size, maximum size differences, and I could go on. So the likelihood you've seen a true labiatus or citrenellus is very slim. Here is TUIC which will clearly show some differences even when juvies.
