In considering what I want to include in a new 80 gallon fish tank, (current stock is a single male Firemouth and single female Honduran Red Point) I'm thinking that it would be cool to find my FM a wife.

He's about a year and a half old and probably just under 3". If I get 3 or 4 females to add in, will he pair off with one (I know it can't be guaranteed) or is he to old and established in his ways to open his heart?

If he does find someone to his liking, and they end up rearing fry, is 80 gallons enough room for other fish (HRP and possible Blue Acara or similar CA cichlid) to escape their territorial wrath?

Thanks!
