Is this flashing or this aggression from his own reflection?

Agression. Its trying to use its rear fin sword on the reflection.

Theres some flashing also...see the top fina flaring high up then the tail swipe.

Ive seen a Yellow tang leave a gash on a tank mate with flesh showing from that tail swipe

I don't see any flashing in that video. Looks like aggression toward the YT's reflection. My Kole goes through a similar ritual every night when the actinics come on.

My yt swells up every night dorsal fins are up all night. But no agression. Just wants to show the tank mates hes there. No threat no tail swipes with the blade.
