My cichlid layed her eggs - should I introduce a male to the tank?

[CRACKberry!<3]

She is currently carrying her unfertilized brood in her mouth and I would love for my fish of 2 years to have babies I actually just found out she's a girl as well after witnessing her lay eggs and put them in her mouth! Pretty cool stuff!

Should I go and buy a male? Or would he just stress her out and end up fighting and possibly killing the other? I have another empty tank to move the male to in case things get hostile.

Should I give it a try? I've had fish for years and would love the chance! She's a pale yellow with black on the fins on her back. She's a very social fish and would be a caring, yet aggressive mom!
