I was just wondering why some cichlids and other kinds of fish grow bumps on their head?? And does any body know how to make them grow one? Is it just for males or can females get them too? Any explanations will be appreciated! Thanks!

I'm not sure why they develop them (they're called nuchal humps, by the way).
Does anyone know of any cichlid species that are dimorphic and have nuchal humps?
