Do you use any of these for your microfauna?

I'm not sure if this is the place for this question.
So I'm going bioactive wih my ball python's new vivarium, and I asked a similar question here, but no one specified what to feed the isopods and springtails. Could I feed them Total Bites For Feeder Insects, Flukers Orange Cubes Complete Cricket Food, or Zoo Med Creatures? I'm assuming so, but I just wanted to check beforehand.
Thanks in advance.

I don't feed my clean up crew anything extra really. Occasionally I'll throw a few leaves in my bioactive setups. This creates some extra pockets to hold moisture longer and gives the clean up crew something to gnaw on when other food is scarce. It usually takes a year for the leaves to break down completely.

Best food? Your typical common mushrooms at the grocery store. A slice of mushroom is like candy for micro fauna
