Six Line Wrasse behaviour

[Bob I]

I have this Six Line Wrasse who puts on a show as soon as he sees me. He stands on his head, flares his fins, and all sorts of interesting behaviour. He does this from quite a distance. At first I thought he was seeing himself as a reflection on the glass. This appears to be untrue, as I spend a lot of time in front of my computer less than six feet away from the tank. Anyone else notice this :question:

Mine does this all the time :lol:
Very amusing dance.

Ditto...

Although in my case I'm not certain it's not his reflection, because I'll see mine do it on a side pane. Unless maybe he's telling off the furnace or the shelves off to the side of the tank. Or he's just generally asserting himself or something like that.
