I would release the male in the spawn tank and the female inside a container in the tank on Wednesday, and release when you can supervise them. It'll give time for the male to build the nest, the pair to get ready, and the infusoria to grow. It's more important to be able to watch over the pair in case it gets too violent and you need to separate than it is to look over the fry.
That's my advise, I never do a spawn if I don't have the time to look over the pair so I usually will release the female on a Friday afternoon after I get home.
Can't wait to hear your results!
