Do Male Firemouths Get A Nuchal Hump?

[pumh]

Like the title says, i want to no though because I have sajica x firemouths and i know that sajicas get them but i'm not sure if firemouths do. if firemouths do, do you think that my crosses will have a nuchal hump if they are male? if the firemouths don't get nuchal humps, will they have a nuchal hump?
Sorry for all the questions
