Leave the male and female in the tank is the best. See how they do. If they have bred before then they should be fine, but if its their first time then they may need some practice.
It would be better for the fish to leave them in their tank. Moving them will cause stress which can prevent them from spawning. Aslong as theres plenty of places for them to lay their eggs, and theres no fish that would threaten their eggs, leave them in.
