Well done paul, I would just leave them be, but keep an eye on them. some times the one of the parents will get protective of the brood, and start to fight, if this gets bad, separate them. But the norm is they will both bring the up together, the female might start eating fry if you disturb them. If you are to separate them, id keep the male out of sight.

P.S
Another thing we have done successfully is once the fry become free swimming, put a young bn in there so the parents have something to take there agro out on. If there is a dither in there tank or in a tank next to them (you know how my tanks are) they are more likely to work together.
