You will want leave the developing tadpole there. Don't try to move it !
Keep a few film canisters ( I leave them on the floor of the enclosures - always afraid they will fall ! ) 1/2 filled with distilled water.
YES! distilled water. ( don't let the water level drop below 1/2. )
The are very good parents !
The male will let the tadpole ( when it's ready ) wriggle on to its back.
HE will transport it to a film canister.
When there, the female will deposit unfertilized eggs into the canister (s) for the tads 1st important meals

I leave the tads in the film canisters for about for about 2 weeks.
I remove them and raise them outside the tank.
Or, you cant just leave them there.
