well it would be better to keep the tank at 80 F. but it does depend on the other fish in the tank, what else do you have?
they should mate, but it all depends on what the male wants to do. i have had a pair for ages and the male finds no interest in the female. but my mollies and guppies mate all the time.
keep the
pH at an alkaline level. yours says 7.5. that's good. feed a mix of flakes, live foods and frozen foods.
please do not use a breeder box/net, it stresses the female out and stunts the babies growth.
your tank is 200 liters? if these guys are the only fish in the tank you could just leave the fry in their as the parents aren't natural hunters. the will target fry if they are hungry, so keep the parents and fry well fed, feed 3 or 4 times daily. you also need some good hiding places, java moss works great.
if there are predatory fish such as angelfish, bettas, barbs, gouramis etc. you will need a second tank, a 10 would be nice for the fry and another 10 gallon tank for the pregnant females. keep the water at 80F and a pH of 7.5.
hope i helped, good luck!
