They're starting to hatch

How soon do I start putting in vinegar eels? I ask because they are like super super super tiny (the babies) practically microscopic. They're are also some of the small worms from me feeding the adults live foods and they're chasing them already. I don't want to soil the water by feeding them too soon or too much, I'm so nervous! Gah! My first spawn >.< Mommy is in her own seperated small tank for recovery and daddy is still in the tank. He's not eating them so I figured it's fine to leave him in there and they're not all hatched yet anyway, like I said, they just started hatching...Any advice or ideas that I might not have thought of to make things go as smoothly as possible is very much so welcome, thank you all in advance
