Tongue Flicking

Since I got her last wednesday, I can't say I've seen my girl flick her tongue. Im pretty sure she did it at the breeders. But I dont know if i've seen her do it. Although its dark when I see her active. Is this normal

I just seen her do it. How often do they flick their tongues when its not around feeding time.

As far as catching her, do what I do. DD is in a glass tank for a few more days and in my son's room. (Technically he belongs to Cody). So when I go in to check on him at night, I check out DD. Cody sleeps through the night light and DD doesn't seem to mind the low level light, but it's enough to see what he is doing. Then I tuck my boys in and go to sleep!
