Yesterday my golden knee was doing this bizarre thing where she had her fangs stretched way out and stuck through the screen in the top of her tank. I haven't seen any of the others that I've got do this, but I have seen her do this once before. After a minute or two of this behaviour, she climbs down and goes about her business.
Is there some purpose to this???
Has anyone else noticed their T's doing anything similar???
Here is a pic, it's kinda crummy but hopefully gets the point across:
