Ok, first up thats definently a male. Only true way is to vent, but it's rare a female gets 12". They ussually stop around 8-10" Also, your RD is mostlikely the typical RD/Midas hybrid. I see the mouth and facual features of a Midas while the build loooks more like a red devil.
With Pure Red Devils it is rare that they get large nuchal humps, but will have slight humps ussually. They have longer mouths and larger lips, though not as pronounced in the wild after acouple generations removed from the wild. Here is a Video of a pair of pure Labiatus.

With Midas, they tend to get larger humps in which females can also develop them. My female's hump gets huge right before breeding. So weather your RD/Midas has a hump is irrelevant when it comes to sex though males tend to have larger ones. With my pair it is the oppisite to my dissmay, lol. Also, mounths are rounder and snouts tend to be less pronounced. Several things can affect hump. Size, Diet, Genetics, temperment, stress, breeding, ect. With my F1 Pair, my male's hump rarely swells. With his offspring, the dominent male from their first batch is already sporting an impressive hump at 6". Here are a few Videos of some pure Midas to give you an idea.
F1 pair from Rapps.
