So here's my set up. I got an unexpected spawn today but I thought it was worthy of posting as a tip.
Set up:
16 quart plastic tub filled halfway
cave
one umbrella plant
heater
lid for the nest
plastic cup with holes
The Pair:
The male was allowed to swim freely in the tub. The female was placed in the plastic cup. They were fed Hikari Pellets and frozen bloodworms for 3 days.
The Release:
I didn't release my female..she jumped. But if I had I would've done this. Within a few days the male should've begun a bubblenest. When it's a good size you now need to focus on the female. I feed them a lot. Once she looks nice and fat and displays breeding bars (light colored females won't) release her. My pair was spawning within a minuet (I think I looked and she was still in the cup, I looked a minuet later and see them embracing). Sometimes they may get right into spawning...sometimes they don't. A lot of aggression can come out of certain pairs.
