I have recently purchased another African Clawed frog to go with my current Albino African Clawed Frog.

I have noticed that this one, who is wild coloured, certainly seems to be wiggling his nose a lot, as if he is sniffing?
I am hoping this is normal, but my older frog doesn't seem to do it anywhere near as much? Is it just because he is new and getting used to surroundings?

Thanks in advance for any advice!
