I feed banana worms, microworms, and baby brine shrimp... Anything that is not alive will go uneaten while they are so small. I remove the male. It's just one less thing to worry about.
It depends how big the spawn is... If you only get 30ish babies then there really is no need, but they should be put in a grow out/divided into two or three ten gallon tanks if you have a whole bunch of babies. If you need anything I am happy to help!
