Absolutely nothing. It's extremely unlikely - essentially never - that the first spawn will be fertile. Even if it were and you actually got free swimming spawn, the rams will get them. More likely, the male won't be fertile for another 3 months. So you'll have plenty of time to get a breeding tank set up, cycled and ready if they spawn again. In the meantime, I would take a water sample to your LFS to document water parameters.
It's the start of an exciting journey!
