New Zealand Tadpoles

[Debster]

Hi, I am new here and I don't know very much about tadpoles at all. We have been given some tadpoles from a friends pond, there seems to be two very different tadpoles in there. The larger ones are almost green, I can almost see the frog they are going to grow into (common for the area, what ever it's name is, green with gold). The other single lonely tadpole is tiny, less than 1/5 the size of the others and seems very black. It seems to behave differently also, hiding more, and when I changed their water it swam the opposite way to the other tadpoles (more natural instinct by the looks). Can anyone tell me what this little guy might be called? Is he just a younger version of the others or a different species? I know he is not a native as they don't have tadpoles.

Oops, just realised I put this in a funny place. Sorry I haven't done this before.

If the bigger one has a green stripe down the middle of it's back and has bumpy skin then it is a Southern Bell Frog/Golden Bell Frog (Litoria Raniformis).
If it does not have the stripe and has smooth skin then it is a Green and Golden Bell Frog (Litoria Aurea).
The small one is a Brown Tree Frog/Whistling Tree Frog (Litoria Ewingii).
All 3 species are native to Australia and they are the only species we can keep as pets legally.
