What kind of frog is this

[purple5262]

Please help. What kind of frog is this? I got it as a tadpole and it has just fully lost it's tail. I was told it was a leopard frog but it looks nothing like the leopard frog it shares a tank with. Any help? Do I need to separate the two? I got the leopard frog as a tadpole also. It's only been out of the water about 2 months so it is still pretty small.



Thank You!
