You can buy starter cultures for vinegar eels, micro worms, and whatever else you want to feed live online
. Same goes for brine shrimp eggs. You have to feed them when they have just hatched... So from the time they hatched, they are good to go for twelve hours. Air pumps reduce waste greatly. Hatcheries for BBS, micro worms, and vinegar eels are easy! You can look it up online... There are tons of youtube videos showing you how to start them! You should get live plants, because they produce infusoria which helps feed the fry!
Hope this helped!
