I have been wanting to get good pictures of my single long-nosed angel, specifically catching the iridescent BLUE on the gill area and on the pelvic fins, and the RED on the unpaired fins. Alas, I can see those colors, but they don't come out well in pictures.
Today I was able to get better images (below), which although still don't do justice, are better at showing the blues and reds.
I still need to get a shot with the colors plus all fins fully extended. It has proved elusive.
Cheers!
