A little help please

[Leanne]

This is the container I've set up for the froglets to go into from the tadpole tank, and also some photos of the variance between the tadpoles, the photo of the single tadpole is a bit blurry but the red in the body is why I was thinking Litoria Ewingi. There seems to be a variance in the tadpoles could there be 2 different species or are they just at different stages? I know I have a lot of questions so I do really appreciate all of your hepl
