My 12'' male Red Devil/Midas

Nope, a Midas or even a hybrid gets around 14". When full grown you need a 75g atleast or larger for a single male. This could however work for a female as they top out around 10"

Are you saying a 55 is good for a adult female?
 
how can you tell if it's a midas or even a red devil? what are the characteristics?
