?odd behaviour or normal

[Newbe]

Hi, my female gecko has started to lift her tail and wave it from side to side. She is one of three geckos with a male, fit, healthy but a little overweight. Is she marking her area??? X

it could be a sign of aggression towards the other females or the male could be wanting to mate but she might not want to.

I believe flagging is a sign she feels threatened by a preditor.
