Great looking fish, and the exposure looks good, did you crop it? Tough to get active swimmers but if you moved Tangy off center a bit (rule of thirds) and had a bit more border around him it would be a great pic.
Yeah I did crop it, he was in a spot in the tank that had a bunch of pest anemones that I have been having trouble getting rid of and I didn't want them in the picture.
I have taken so many pictures of this guy and this is one of the few that he is not in a blur.
I have an HP315. It doesn't have many features so my main technique is to take tons of photos to try and get a few nice ones.
