Red Sea Sailfin Tang

[sonicfish]

I look at my tank and saw that my red sea sailfin tang was a very dark color and i was wondering what that means but came back in 5 minutes and bright colored again so what does this mean

Don't know if I have ever seen one darker but many fish get lighter for a few minutes when they are startled or stressed. I would guess it is something similar.

my damsel did that when i trapped his lil punk butt


i think darker colors, and maybe a low fin display in fish world means P O'ed
