My Soon to be Froglets (still have tail) do not seem to eat Pellets is this Normal?

My Soon to be Froglets (They have started to come out of the Water but still have their Tail so they are not yet ready to be transferred from the Deli Cup to the Terrarium) do not seem to eat Pellets.

Is this Normal?

I know they get nutrients form their Tail still right?

Is there something else they will eat?

Or do they just go from Pellets to Tail to Fruit Flies and Springtails?
