I didn’t but there wasn’t that much in the tank, if there was flow on the coral I would have turned it off but I had a really gentle breeze type deal in this situation, the photos is the same in he sense of the head, they are different tho if you look super closely you can see the differences. I just turn all the blues in the second pic and the first pic is all blues with whites. About Photography I will say it’s something you work at and a lot of research. YouTube was my best friend.
