Sprintails and tropical woodlice?

[hereces]

I'm starting to put together a natural WTF terrarium very soon and would like to add some springtails and woodlice for custodians.
The terrarium will be allowed to grow for a couple of months before the frogs go in.
My question is what should I feed the custodian insects during this initial frogless 2 months?

Thanks for your time.

I've used fish flakes in a frogless vivarium for springtails and woodlice.

Chop up a mushroom slice and spread around the tank.

^^^That'll do it. Careful they don't explode and go everywhere.

Watch out for mites on the mushroom!
They can have the times of their live with all the food and no predator
