My most successful pair spawned in water about 68'-70'F, and killed all tankmates in a 150 tank at the time.
I found them susceptible to bacterial infections in warmer water, and tried to do water changes of at least 30% every other day, to keep water pristine.
They never liked any other cichlid tank mates, unless they could kill them, and if they couldn't tended to stress out and sicken.
I sent fry around, and warned that even at a small size (1"), they will be very aggressive needing either single separate quarters, or heavy plantings to break line of sight.
A person I sent many, lost them all by not providing this type habitat.
