I personally wouldn't let them see each other during conditioning. There is a chance the female may release her eggs her self and eat them, this is one thing you DONT want to happen, once they eat them they may never stop.
I don't introduce my 2 until they are fully conditioned. the male is added to the spawning tank, half hour to a hour later the female is added in her bottle then 24 hours later is when i release them but only if i think they are ready.
