breeding sevrum cichlids

[Invigor]

anyone tried this, succeeded at it and want to help me try it? i have a "breeding pair" that hasn't bred yet, because we ASSUME there are too many fish in the tank with them, so I have a 48g that I plan on putting JUST THEM in it to see what happens.

do I need a bigger tank? what kind of decor should i have for them? Where do they like laying their eggs? on a flat surface like most other cichlids?
