Hands down guppies, they are easy to breed, low in fat (unlike goldfish), and cheap to get, just make sure the fry don't get eaten by the parents, shrimp are a bit tougher, cherry shrimp breed very readily but are VERY sensitive to water changes, I'd recommend crickets in place of them if you can
new life spectrum is really good, but some fish won't eat pellets and maybe he just wants to see his fish eat live food (if you're into that)I would recommend NLS and forget any live feeders no chance of disease with NLS Nls is also better than any live feeders
