Six line wrasse odd behavior?

[Cooperdude916]

Iwas wandering if this is odd behavior for a six line wrasse but when somebody walks by the tank he jams his face into the glass turns sideways and spikes his dorsal fins up. He hasn't done it in the past 2 weeks but before then he would do ti all the time.

Displaying aggression. Making himself big to try to scare you off.
It's fine that he's not doing it now, but it means you might have trouble adding any more fish to the tank.
