After a pair spawn, unless you already know their parenting skills, its generally a good idea to remove the male, and allow the female to raise the spawn.
I've had many pairs spawn and successfully raise fry together, but had just as many get trashed when the male got belligerent, ate the eggs and fry and killed the female maybe 50/50, and especially if it happens in a small tank..
I usually remove the male when he wanders off to the opposite side of the tank.

With bartoni above, I could always let the male and female stay with a spawn,
but with haitiensus if I didn't remove the male, the fry would cannabalize the male, eating gaping holes in his side
