Hi,
I certainly am not an authority but, I use frozen and live there are many
sources here and much online you could start with these.

I use micro worms and vinegar eels for new fry. Baby brine shrimp for older
fry and adult fish. I am now just using grindal worms for adults. Also many
different frozen cube type foods. I always heard NOT to use black worms
though.
